Guys/Gals: I need your paint restoration advice!

I've used lacquer thinner. Wet cloth in one hand give it a quick rub to remove overspray and quickly wipe dry. Should cut through it before hurting the original paint. I've removed spray bomb paint on a side of a car (vandalizism) by doing this without having to paint .I did buff polish and wax after . Test a small spot 1st and stay away from your good paint. Not for the faint of heart.
