I am at the point on my wood duck hybrid where I have glassed the hull and im getting ready to fit the forms. My concern is the finish of my fiberglass. I have placed 4 thin coats of epoxy over the fiberglass, but it has some run marks and some of the finish looks textured like an orange peel. My question is, should I try to sand this smooth now an apply another coat of epoxy, or should I just sand it before its varnish time. I applied the epoxy with a foam roller, the used a foam brush to smooth out the bubbles, but like I said there is some run marks and ripples still visible.
Any suggetions will be great
