I am just getting into detailing and am using my work car as a practice vehicle prior to getting to my pride and joy vehicle. I am presently using TW rubbing compound(until my AG order gets here next week) on the hood of my black Maz 626. AFTER compounding I am noticing very small little "starburst" looking imperfections. I did not notice these before. Any idea what they could be? They almost appear to be under the clearcoat, not in it.
