Over the last year I have gotten way too many calls like this.
I laid 4 or so coats of clear and then wet sanded and buffed and now I have urethane wave.
Simple answer, you do not block fresh clear like you do a urethane primer be it 30-45 deg angle.
Think about this if doing a hood or large panel, one or two extra strokes stopping in center of panel will make the clear uneven.
Always block clear in a straight long stroke motion.
This is mostly for the do-it-yourself people but if doing insurance work with just two coats of clear, really would not make a difference.
