Here it is boys, something I like to think as the last step in getting a perfect part!

After stepping into the clearcoating/painting business I can tell you, with or without a paint both it is a total PITA. I cant stand clear coating a part after de moulding, then the clearcoat gets wavy or a bug in it. then i san and polish, still not perfect.

I'm starting to learn this real fast; the key to a perfect part, is taking a mould from a perfect part and polishing it there. I plan to make some really perfect molds, then try this.

 



 

The site says you can brush it on, we for my size parts that would be really connivent. Now matter what the surface of the part will be perfect but if your paint strokes on the back are to thick you may see your weave get a little wobbly.

When making parts smaller than ".5 meter" I think my cup gun is a bit much? think an air brush system would work?

 



If Brute Force Isn''''t working your not using enough...

Have you tried a chemical semi-permenant release agent such a easylease or similar?

You will get a easier release than with wax, plus easylease can leave a nice gloss finish if the mould is highly polished.

Ive always found wax releasing is the hardest, but PVA causes surface finish imperfections that need polishing out.

however with easylease ive found if the mould is shiny, then so is the part straight from the mould.

Would kind of maximise the benefit of a cosmetic gelcoat if it comes out super shiney to start with. Plus save you time in finishing.
