I have got the resin infusion process down pretty good now but the parts aren't finished until they have a nice protective gloss to them. Clearcoating direct carbon is hit or miss due to pinholes so I would like to spray a clear gel coat to create the gloss right out of the mould.
Question is:
Is it possible to spray down the clear gel coat, wait for it to tack, THEN lay down the carbon, bag it and infuse?
Thank You

To be honest, I'd forget the idea of using the gelcoat as a surface tack. As brainfart mentioned, applying epoxy to an undercured polyester gelcoat is risky business, even if the gelcoat is formulated to work with epoxy. Normal practice is to allow the gelcoat to cure for 24 hours before infusing. Whilst it is possible to use the tack of the gelcoat to lay your fabrics and then allow it to cure fully before infusing, there actually isn't really a need. Spray adhesives applied lightly behind the gelcoat will not affect your surface finish, they will be invisible.
