I’m loving these videos. It’s always hoped everything goes smoothly when respraying a car, but as, you’ve shown, don’t panic, let the paint dry and tackle it later. I thing the spot on the front corner may have been a brush with the air hose. It happened when a friend was repainting my son’s Racing Green and the hose had a curl in it which touched the fresh paintwork. It was spotted when the paint was still wet so it was simply blown in.
Great question & observation. If I’m honest, I gunned on a sealer round the whole car initially so it was 90% covered. These last few bits were either addressed after I’d primed or just missed 😁
