I got my Firebird blocked and ready for paint. I was going around the car spraying the sealer and then I got a huge amount of dry spray on my fender, hood and door. It looks like sandpaper. I've never used a sealer before, I imagine the coat is thin. Should I block out the dry spray and then lightly block the rest of the car? The sealer is sprayed over a mix of polyester primer and spots of glaze.
