Auto body paint supply mixed up a quart of SEM for me, and I sprayed a pair of green '68 Charger seats white, and they held up great. Couldn't tell they were sprayed, even in the pleats. Just wiping with a solvent just dilutes contaminates like Armor All, or whatever. I use trisodium phosphate, which is a powder, with a Scotch Brite and water to scrub them, and wash all contaminates off.
