Hell, you have to wait 3 months just for it to fully dry. They shot straight enamel, no hardener.
Had a customer put a car cover over a month old paint job and it fused to the paint. He brought it back 2 montths later and paid us paint it again...dumbass.
I'm painting all my projects going forward. I'm sure my efforts would look a **** ton better than some of the 'budget' paint jobs.. And certainly no worse than what I'm starting with..
