or try tightening it some before loosening it, i've heard this work. impact wrench and dont be afraid to crank the biatch to 120psi plus instead of the 90 alot of impacts recommend. other then that letting some liquid wrench sit for a long while. our cats do the same shit, they sit on the car in the winter cuz the sun reflecting on it makes the surface warm then they claw the shit out of it or leave muddy paw prints. im glad i have a garage for my 240 now.
