I recently did some pinstriping on my bike. First time playing with this stuff. Went to an autobody paint supply store. They recomment a sign paint. That's what I used,he may not have used that. I cleaned off the area first with a little acidtone. Then I pin striped it. Let it dry a couple of days. Then I went over it with TurtleWax Glass, clear wax/sealer. So after having the pin striping on it for a couple of weeks the paint was dryed pretty good. Some of the striping I did not really care for. I used some acidtone on the pinstriping. Let it soak on the parts for a minute and commenced to rubbing. It came off ,not the easiest , but it did come off. Then I rewaxed the area I had just rubbed the pin stripping off of . It is worth trying a little acidtone and elbow grease if it works, it was cheap to remove from the bike. If the guy used some other paint and had it clear coated on top of that good luck getting it off.
