paint booths & body shops. what to use? (paint build up)

[El Flojo]

I clean my uncles paint booths for free and (only the floor) i use a big scrapper on the thick stuff and a hammer and chissel it just to break it up a lil then the turbo works fastest. wear prop[er ppe paint will fly. then just rinse them out. I clean them twice a year and they are pretty bad with build up. good luck
