My goal is to make some single layer flat sheets that are UV protected.

My thought is to use a Polypropylene Sheet, use a roller to lay on a layer of GC50 Gelcoat, let that set for the 2-3 hours, lay down a dry sheet of CF cloth, then wet that in with the epoxy resin, place another Polyproylene Sheet on top and them clamp them together.

Is that the right approach?  Will the GC50 be enough UV protection or would it stil need a spray on UV Laquer wet sand/polish on top?  I'm trying to avoid that extra labor.

 

Thanks,

Eric

Similarly I have consistent success producing sheets on a sheet of glass (flat rear hatch screen).
I use easylease + wax for release and infuse the stack with peelply and normally infusion mesh over the top before the vac bag.
Works great and the glass surface clears up quickly for re-use.
