Epoxy surface coat in a mould

Hi!
I'm moulding some small epoxy/glass parts in some home-made female moulds.
I'm wondering about applying epoxy surface coats on the inside of the mould like you would do a gel-coat in a polyester layup. I'm interested in doing this so I can come away with a thick, smooth epoxy layer on top of the fabric that a) looks nice and b) I can do cool stuff like glitter-ize or color (same reasons people gel-coat I imagine).

Do people do this?
How is it done? I'm imagining something like mould->wax->pva release film->coat of regular epoxy->first layer of fabric/resin. Any special techniques? Should I use something other than plain old epoxy?

 

Epoxies don't weather that well, they tend to become dull and turn yellow very soon after being put out in the sun, that's why they aren't frequently used in this way. There are epoxy compatible polyester in mold coatings that can be used.

 

If you go with prepreg they have sheets of epoxy which you lay up first to give you that extra layer. People also use clear coats after the fact with metallic particles etc
