I've read it's not necessary to use paint stripper on fiberglass, and to just primer it. However, the clearcoat on my spoiler, is flaking off and I think that primer will make it lumpy. So what are my options?

Should I sand off the clearcoat, get clearcoat remover, or primer it, sand,primer,sand until it's flat?


Any thoughts would be appreciated. Thanks!!

 

Sand it off then prime it.
