Peel ply is dry brushed on top of a wet lay up and soaks up resin from the lay up that will wet out the peel ply. When removed it leaves a pattern on the lay up equal to the weave in the peel ply. This is a slightly rough surface that requires little if any sanding for a follow up layer of glass or very little fill for the finished surface. I recommend using peel ply on any lay up where you have one layer of glass overlapping another. When brushed on, the peel ply draws the resin up to form a bridge between the two layers and practically eliminates the "edge" that would require filling if the peel ply is not used. The two inch wide roll of peel ply works best for that purpose. Some builders use peel ply over the entire lay up. They purchase the "Dacron" cloth, or whatever it is, from a fabric store. The "deck cloth" does basically the same thing but remains as part of the structure. It's weave is fine enough that it requires little if any fill or sanding before you start with the primer for the finishing process before painting. Larry Flesner
