I get this sap on my car from the trees and it doesn’t come off a guy at the car wash used this stuff and it took it right off ! So I came home and bought a cannon eBay and it’s great! I tried everything this is the only thing that works
I purchased this product to remove some markings, spray paint, on metal garage door.
I tried on backside of the door, and it didn't bother the paint. But, when used on graffiti it softened to the primer. I then was forced to repaint the door.
I wouldn't recommend this product for removing graffiti from a painted surface.
