Fiberglass Pultruded Profile Samples With Peel Ply

Our factory has tested two kinds of profiles with peel ply. We use peel ply with the highest heating temperature 220℃. The 1st one is fiberglass pultruded u profile peel ply off and it's painted directly, the 2nd sample is frp u profile peel ply off but with puttying before painting. Test result is: there are peel ply stripes on the surface of the 1st fiberglass u profile sample, but the surface finish of the 2nd sample with puttying before painting process looks much smooth and noble.
