i use it all the time. used it on 4+ cars never had a problem. its enamel paint like everything else there. made in china like everything else there. the only paint better (in a can) is the rust guard stuff because in the mix it has de-oxidisers.
truth of the matter is youre always gonna get an average job out of a can. i just gave him a cheap option that i have used many times before. the spray technique was really what i was trying to focus on.
that septone stuff is probably the stuff to buy if you dont want to use a gun.
