single stage urethane will buff out fine,, the thing is is not digging in deep,,, usually the last coat on a metallic is the one that makes the metallic even looking,, if you start to dig into the paint with sanding you run the risk of seeing paint lines or thick/thin spots of metallic. Cleaqniong all waxes/silicones & a light scuff (like a Scotch Brite pad)of the existing paint & a clear coat would be a better way to go,, IMO.
BTW,,,, I consider myself in no way an 'expert'
