What Happened To This Paint?

I've just painted the radiator support area, and got an area that is 'spotty'/grainy. Just thought I would get the opinion of some pro's as to why this happened? It is the same on both sides. I went back to bare metal, etched, surface+high-build primed, then put on the black. No sanding in between (I don't think this area is that important). My guess is it is overspray from high-build that built up after spraying the vertical surface that is parallel with the radiator.

I think you're right, and it's overspray that's gone on half dry. Buff it back?

Yeah its either overspray or severe solvent-pop by laying on too many layers too fast without letting it flash off in between coats. Most likely just sprayed on dry (overspray)
