you have me laughing, what the story on that Hi tech paint job ?
people I know use I think an oven cleaner, it's called orange something ??? it's a gell they rub it in with a rag, to wrinkles up spray paint then asap use a plastic bondo spreader to scrape that off. it does not harm the original finish. There doing this on old cars that have been pained over, to restore that cars original paint .
having very good results of not harming and graphic under the spray paint .
from the looks of what was taped off, it's hard to believe rest would have been very bad..
course another can of Gold and call it Goldie , Golden jonsie , Jons'n fer gold
