The first time that I used RaggTopp I left the overspray until the next day, and it was definitely a PITA to remove. My next time I opened the top slightly, draped towels over the windshield and side window, and closed the top - masked off the rear areas and the rear window. I still got a little overspray on the paint and rear window, but found that if dealt with immediately after finishing the top it came off easily with a little QD. So, now I just use a small (maybe 6”x16”) piece of cardboard as a shield while I spray - and make sure to deal with any overspray promptly.
