Complete beginners question what are the differences? Is there an advantage using one Over the other? I've only heard resin being talked about since I camback to the scene. Thanks lads

Definitely no expert but hopefully I can give you the basics... In general, plastic is used for large production runs by bigger companies, and resin is used in smaller production runs by smaller companies ( as I believe it's cheaper ). From your point of view, resin may need a little more work to get it ready ( i.e. getting it washed, sanded etc. ) and instead of the little 'sprue gates' attaching the plastic piece to the sprue, the resin pieces might be part of a larger 'lump' of resin so they'll need to be cut off that, then sanded down. Resin can be a bit more brittle and easier to break than plastic. Also, I believe the dust when sanding Resin is harmful, and should be done in a well ventilated area / wearing a mask etc. The other main difference is you'll have to use SuperGlue or Epoxy for resin, standard liquid cement won't work. Apart from that, it's possible ( but not always true ) that resin pieces may not fit as nicely as plastic pieces ( depending on the kit of course ) so might need more sanding / shaping to get them right. In general, it's probably easier to make a plastic model, and while I haven't attempted a full resin kit yet, I do have one, but I'm glad it wasn't one of the first I tried after getting back into modelling. Even now, looking at it, I know there's gonna be a fair bit of work to get the fit right. Of course, that's just *this* resin kit, not all of them, and you can say the same about plastic kits as well. But, if you're looking to make a kit of a lesser known subject, resin could be your only option! I hope all that makes sense, and anyone who knows more than me about resin ( which I imagine would be a lot of people ) can correct any mistakes! Thanks! J. On the bench - Revell 1:72 F-16B

In general, I would recommend that! But it is in general, I'm sure you can get a great Resin kits and almost fall together and I know you can get crap plastic ones! :) But, for me at least, I'm happy building plastic ones, as I feel it's easier and should has less fit issues etc., and it's a material I'm more used to working with. My Resin kit is the 1:72 Firefox, which isn't really available in plasitc. From what I've seen of it so far, it's going to need a lot of sanding and filling to get a nice smooth finish, not something I would have wanted to do back in January when I got back into modelling! In fact, not something I really want to have to do now either, but at least I feel now that I can hopefully handle it! :) J. On the bench - Revell 1:72 F-16B

I agree with Jason. There is a world of difference. You know the plastic already - all I can add, as a fellow returnee, is that the quality of much of the plastic now is better than it was in the old days (well, with some of the manufacturers.....).
Resin generally, in my experience (two kits and a lot of aftermarket goodies/add-ons so far!), is much more difficult to do. First of all, the resin has cast blocks, which have to be sawn off (you need a razor saw) and then the parts need to be cleaned up. Where there are smaller pieces, they can be cut out from the surrounding matrix (kinda like a spider's web), or the whole thing can be sanded (eg for cockpit side panels etc) until you just get the bits. Many smaller bits are extremely brittle, so no matter how you do them, they will split/break.....
Second problem is that the dust - when sanding, sawing etc - is toxic to humans (and any pets you might have around). So you need a face mask, or just sand under water water. (Fido has to be put out when working.....as he/she doesn't like a face mask)
Third problem is, as Jason says, that you cannot use the usual glues - revell contacta, tamiya extra thin etcc - you gotta use epoxy or superglue. That means more hassle getting things to fit together.
Fourth problem is you often have minute bubbles on the surface of the resin (especially problematic on wing leading edges) which have to be filled in with a smear (or more) of filler, and then smoothed out with sanding (again needing masks or water)....Then you absolutely HAVE to prime before painting (you can often get away with not priming on plastic kits).
Fifth problem - from my limited experience, is that the fit of resin can be a bit worse than most plastic kits, so you will probably be doing a lot more sanding and filling than with - at least mainstream - plastic kits.
So my honest advice is - unless the model you want to do is only available in resin, go for the plastic model every time, if you are thinking kits rather than additional pieces etc.
However, some resin pieces/correction sets etc, are VERY good, and can liven up an ordinary plastic kit really well. I have lots of kits with resin add-ons, usually (since I do planes) in the cockpit or the wheelwells. I understand our vehicle brethren use a lot more of them. Maybe Pat or Fise, who are acknowledged experts in this area, can give you their experience on those.

I wouldn't call myself an expert but I do have some experience of resin kits. The advantage in using resin kits is that some have added detail that is beyond inction plastic moulding. Also most kits not available in plastic yet can be found in resin. I would say the first thing to do when choosing a resin kit is look for a review. There are acknowledged first class resin kit and after market producers out there who provide top grade bubble free kits but there are also resin kit producers who should be avoided like the plague either because their kits are rubbish or because when you send off your order and money you might never hear from them again. so look for a review or ask for opinions here about specific kits. If you do decide to take the plunge and go for a resin kit then the best saw for resin is this one from JLCResin Dust is dangerous if you are breathing it in (as is any dust) but it is inert and not dangerous to touch. When working with resin I use a jar or tub of water and dip the saw in which makes the dust clump together and fall away when dipped again. If I'm sanding away a resin plug or to make a piece fit better then I will continuosly dip the piece in waterFor gluing I would use a low viscosity super glue which has a longer drying time.

Jesus lads fair play for the detailed answers, very very helpful, I think I will stay away from resin then for a while until I have upped my skill/patience level... Again thanks for taking the time to write such in depth answers

I'm no expert on resin either, but again, I have had some experience. Even if you stay away from the full kits (such as Fisher models beauties) you'll probably find youself buying an aftermarket detail set for something somewhere down the line, and again, quality and fit will vary. Advantage with resin is that it is possible to get hold of some really obscure bits and bobs that it isn't economical to produce in injection mould, and also there are some very knowledgable people out there that will produce correction sets in resin for the parts that the kit manufacturer should have got right in the first place. Cockpits, wheel wells, and ordnance are big favourites, plus weighted wheels. Some resin is very brittle and whilst taking good surface detail will shatter if you look at it funny, and some is quite soft and pliable. Oh, and it is also often possible to straighten warped/bent resin with a bowl of hot water, as it seems to retain a kind of mould memory. (although my MkIX nose was so far out I ended up using it as a shell to build up/sand to shape - nightmare 4 weeks work  ). All in all, resin very useful, but can be a pain to work with.

Yeah, it's all down to manufacturer. You have some of the classic names, whose products are spotless and details on them are beyond the wildest dreams, but you'd pay top dollar for their sets. Then you have plenty garage manufacturers, where you have to be very careful what you're getting as the quality can be very bad and not worth the money and hard labour, but it could be top class too. So inspect before you drop some change. For quick introduction to the resin, I would recommend some easy sets, which are made as a direct replacement for the kit parts, like ejection seats or Quickboost line of resin goodies: http://www.quickboost.net/catalogue.htm

Great discussion and good hard facts. @Pat From what you said it looks as if one needs the saw you linked too. No good trying to cut with a knife. Has anybody tried the mini-drill saws for separating the resin bit from the block? @ Filip: Thanks for the Quickboost link, I notice that most of the stuff is made for specific kits/manufacturers. I read recently somewhere that it was a waste of money buying a part suited to one manufacturer and trying to get it to fit a different one. Anyone had experience of that or was it just a marketing ploy? thanks again

Well you don't need it- it just makes life easier. I have a one and a half inch scar on my left index finger I got when the craftknife I was using, to seperate a resin figure from it's plug, slipped and sliced through my finger  I mostly use the JLC blade without the handle. They're quite cheap and each side of the blade has a different grade of teeth. There are other razor saws out there and I used to use a junior hacksaw but I find this one to be the best as it makes a really fine cut and produces the least amount of resin dust. When you say mini drill saws do you mean the dremel motor tools and similar? - they would work but you should use them at the slowest speed possible to avoid making clouds of dust

Thanks Pat, hope the finger was duly "glued" together, After a health warning like that I better get a saw. Yes it was a Drenel type yoke I was thinking of using. I got as a trade back in the 1970's, several full solid resin kits from a Czech modeller on exchange. Great moulding but I remember trying to drill out the cockpit! Never finished them.

Anyone had experience of that or was it just a marketing ploy? thanks again The thing is that the resin detail sets are designed around certain kit and as a such they are recommended for that particular kit, but it not necessarily means that they must be used only with that kit. For example, if you are getting sets/replacement parts for a Hurricane in 1/48 scale you will get sets designed around Hasegawa kit -as this kit was/is the best on offer in that scale - and they will have that 'recommended kit: Hasegawa' clause on the box, but it doesn't mean that it will not fit into Hobbycraft or new Italeri kit. Some modifications to the kit and/or resin parts pending. Then you can get the generic sets, like ejection seats, engines, gun barrels, wheels, guns and so on intended for universal fit. But! As those are scaled down versions of the real things you must be prepared for an eventuality that they do not fit as snugly into your kit as the original kit part and some radical shaving and thinning of the kit's plastic might be involved to make them fit. From my own kitchen, I have fitted interior set designed for Dragon StuG IIIC/D into Tamiya StuG IIIB. It did fit with minor changes and, eeeeeh, after a few weeks of work looks spot on. I was backdating the set to suit earlier version of that artillery yoke too, ya know...

Even resin AM designed for one kit may not fit properly, especially if you aren't doing the exact version it was meant for. As an example I bought Heritage Aviation parts to change an Airfix MkV to a MkIX, but the replacement parts were destined for the late version MkIX and I was building an early. To cut a long story short I have a lot of spare resin parts and the main part I wanted (the nose), no longer fit properly because the carb was the wrong length. Resin is very useful and can be very well detailled, but expect a bit of work to get it to fit

Have to agree with that! I got a CMK Resin cockpit for the Airfix 1:72 BAe Hawk. It was a cockpit for the exact kit I had, and was still a git to fit! J. On the bench - Revell 1:72 F-16B

Thanks for the follow on info - v useful, but I think I'll stick to the plastic for a while, anyway I am "restoring" some of my ancient kits, anyone try Fairy Powerspray to remove old enamel paint? Well I have got a Spitfire which had two coats (different) of old style Humbrol as good as new using two sprayings. Amazing what household stuff under the sink can do!!

Fairy power spray? Now there's a new one. I did read of one guy who had some success using foaming oven cleaner...but i'm not sure it wasn't a wind up, so Ive stuck to sand paper and elbow grease so far.

Fairy Powerspray is the way to go. It's not as severe as Mr Muscle Oven Cleaner and seems to strip metallics a lot better too. Make sure you put the model in a container (or plastic bag) which can be sealed and made airtight. Don't just spray the stuff on and let it to air dry... it loses its effectiveness. Spray it on covering all of the model and put the lid on the container then just sit back and leave the spray do its work. I've left it on overnight without any ill affects but and hour or so should be more than enough. Then wash under a tap with a toothbrush (to remove gunk from the panel lines) and it should easily come off... if it hasn't already done so in the container. It won't cause any damage to plastic or resin. If the paint is years old then reapply the Fairy Powerspray until it's all gone. Mr Muscle oven cleaner (foam stuff) works well too but I've found it to be harsher than the Powerspray. It attacks fillers a lot more than Powerspray but it is good for the tougher jobs with paints baked in over years. Fairy Powerspray is my weapon of choice when restoring an old model. Removing paint with sandpaper is a big NO NO!  Goodbye detail if you're doing it that way. The oven cleaners will leave all detail intact.

Vinny & all, One small but important thing I omitted from my posting on the Fairy Powerspray, is that I found that some of the smaller parts i.e. the spinner, tail wheel and other small tiny bits tended to come off during the process. So when washing it off, suggest adding water to the bag first, don't worry about the mess, just look for the tiny bits. If possible use a small strainer (from the kitchen when nobody is looking) and strain it out. Then if you are missing any bits - poke around in the strainer.
