Seam sealer. I've used and like the Eastwood stuff. May I suggest: 1-primer then seam sealer, flatten down a bit with a throwaway brush dipped in lacquer thinner. 2-after cured then finish paint.
Thanks for the advise. I saw a post from a couple years ago of a place that would put QQ1 paint in a rattle can but now their site only says they do motorcycle stuff. Color Rite I think….anywhere else that will do that? I just want to creat that factory overspray look back in the trunk after my surface rust removal and protection.
