Hi, can GC50 be used as an in-mould clear coat to then lay up prepreg on?

GC50 can be used under pre-pregs although the manufacturer recommends you cure at least 85C to ensure proper adhesion so at 90 you should be ok.

Sorry Warren, should the prepreg be laid up after a postcure of 85 or should GC50 postcure together with the normal prepreg cure?

Layup GC50, allow to cure as you normally would for a minimum of 2-3 hours, lay up pre-preg then cure on pre-preg cycle.
