Was able to heat my garage to a constant 70 degrees F. Laid down 2 wet coats of 2k primer. What's best to do? Sand to 180/220 and final primer coat and sand/block again?
Last coats of primer was completed and the car was blocked to 220 grit. Tomorrow I will complete to 320 grit!
I wouldn't use anything heavier than 400 grit prior to top coats. the sanding scratches will show through so the finer the paper the smoother the final finish. Prep work is always the hardest part of a paint job. Spraying is the easy part but it helps to have some experiece laying down the top coats to get a superior outcome. Everyone has to start somewhere.
