I am new to fiberglass boat mods and am currently working on my first project. I was curious if on pure cosmetic pieces of wood that will have no wear or weight do I need to use fiberglass with resin or could i just seal with resin and paint?
It depends on the wood. If it's a hard wood that is not prone to checking (a rippled scaling and splitting effect that will happen to softer woods without a layer of glass) then a few coats of EPOXY, not polyester, followed by varnish or clear coat will be ok. If it is a softer wood like white wood, douglas-fir, or most plywood, then a layer of 4-6oz cloth will keep the checking at bay and won't effect the looks at all.
