It's lacquer checked hard core, so yeah, it needs it. I wound up partially stripping it using the stripper and letting it sit only long enough to start bubbling the paint ( 1-3 minutes) before scraping it off with a putty knife. I am now in the process of smoothing out the remaining paint with 220 grit wet or dry wrapped around a paint stirring stick, and will follow that with a 3M #20 soft block that I have for curved areas. I figure that I will prime it in etching primer first, then Nason Select-Prime 2K primer before the final blocking. I just wish I knew that it would not damage the FRP because I would let it strip all of the paint and save my fingertips!
