I painted my trunk and apparently I didn't use enough clearcoat because 1) It's very matte looking and 2) it has orange peel. However, I painted the trunk over a month ago (I haven't had time to get to it since), so everything on it is pretty dry on the surface. What should I do to fix it? I was thinking I could just wet sand the surface and put more clear on it, but what grit should I use? I used 400 grit when I wet sanded the primer, but I was told I should use something like 4000 on the clear. Or would I be better off DAing the whole thing down and doing it over again?
