Sounds like that darn $10 jumbo can of Nut BusterI got at friggin WallyWorld other day. Sprayed a little one time and it was done/ Taking it BACK!!!!!!Those cans are from around the time when they had a lot of issues with the cans. Some of them wouldnt spray at all and some would die after about a half can. Just an FYI, this may be how he ended up with them at a bargain price.
I stopped using the MP paint because it doesnt hold up. Antifreeze will discolor it and even soften it.
