I've recently had my f/bird painted and the clearcoat never really got smoothed out all the way . My nephew painted it and it looks great but the c/coat had runs in it . On the sides I can notice the wavy areas in the right light . It's shines but I'd like to smooth the surface out if possible . Would I be able to use some 1500 s/paper on a longer s/block then step up to 2000 s/p to finish and then wheel it to a finish ? He's been busy w/kids and things and I thought I might be able to do it a little at a time but I don't want to mess it up and have to c/coat it agin ???
