I have a car to work on this week that has a massive amount of white line paint on the lower part of the car. Fenderwells are covered as well as the rocker panels and even the tires have some on them. This paint is very thick and hard (been on for a couple of months) so clay won't begin to touch this stuff. I have used a plastic scraper or razor blade in this past but this was for much smaller amounts. Any tips would be appreciated. I'll post some pictures as soon as I can. Thank you, Dan.
