Thanks for the responses everyone.
Ira, great news for me about Polyurethane, that is a product I often finish the models in, as the matt coat is very good. Does the Polyurethane over time wear thin with water corrosion, and eventually come off?
si_sphinx, good to hear any type of paint is fine, so long as it's sealed in. The epoxy resin you're talking about, are you able to get it really thin, or does it have a tendancy to be quite thick, and cover up any detail that I might have added? In regard to building models for a job, I've got heaps of work to supply me a weeks income (infact i've got a $4000 backlog), whilst I finish off my flying instructors rating. I used to be into R/C, when I managed a hobby shop. Part of the job was to build them every now and then, and demo them for customers, but thought I'd give the real thing a go, which I have no crashes with... but costs heaps more! Ha :-)
suphew, are you suggesting if I were to glue the model together with CA, and use enamel paints without sealing the model it will be fine? This would be fantastic news.
Just one final question, do you think there would be a market for good quality wreck models, rather than the nasty looking ones that you often see at pet stores? I'm thinking 1/32 scale models about 40cm long, with panels missing and framing showing, large enough for 5cm-ish fish to hide in. I think I could build them for around $350-$400. Or is that a bit over the top for you kind of hobby?
Thanks again for all your help. I'll be sure to post a link of the finished product as soon as I've finished it.
Cheers, Alan
