I am sanding my bumper down to repaint it becuase the paint was chipping and looked bad. I am going to make it black again, but should I add a clearcoat to it or just leave it as the default semi-gloss? btw, that weird coloring is because I started sanding the top black layer off and there's a blue metallic layer underneth. This is what I've done so far:

 

if our shooting base clear you have to use a clear,

but from your question i am assuming your rattle canning the bumper..is that correct?
