Well I am very new to this board but here is something I've been working on. There will in the near future be uv cured finishes that can be cured in seconds with the right light. The reason I mention this on this thread is a product I been using to make eyes is just that a uv cured polymer. When cured it is clear and stays like that. These products came from a black syringe to protect it from sunlight as this light will cure it. The first time I saw this material was in wader patch form from loon. Now in fly tying,Tuffleye is the product.It has two consistancies core which is thick and finish that is thinner. One draw back with this product is that after it is cured it has a film on top which i remove with alcohol.This dulls the surface but I finish over it anyways.You can build up as much as you want,work it ,turn it ,push it, pull it but when you put the light on it is cured.The eyes I want are bigger than I can find so I just make them. They might be a little expensive at first but when you have the light the cost is minor. Hope this brings new light to this subject. Wait till the clear coat comes out in spray cans!
