Hi

 Forum newbe here with hopefully a simple question, I'm not a newcomer to composites having owned fiberglass cars for 30 years but I could do with some advice

I've been rebuilding some old fiberglass doors for a hillclimb car i'm building. they were damaged when the car rolled a few years ago and I'm using them on a new one I'm building. I've had to make new window surrounds, repair where the hinges got ripped out etc and they are now structually repaired. Due to the various repair methods I would like to skin the outside surface with a thin layer of cloth and an epoxy resin to give a homogeneous outer layer, to hopefully stop the repairs 'showing thro' . What would people recommend for the cloth and the epoxy for this job?, bearing in mind minimum weight is a factor on a competition car. Also, after adding this skin, what would people recommend as the next layer to prepare it for paint?, spray filler?, gelcoat?, etc.

Cheers

Eric
