i had a bunch of old pimer sealer laying around some old corlar and some gaserite. no reducer or activator.
i was woking on my bucket and had done the framework for the floor out of square tubing i was just going to paint some undercoat on it and be done with it.
i looked at this old primer sealer and decided to just paint this stuff on as i was god it stuck and dried slowly but doesnt look any different that the primer i laid on the t bucket body that was acivated. it even sands nice .
heres my question. is the acivator in a 2 stage paint for production and speed only or does it acivate a hardener in the paint itself that will not acitivate if air dried.
i built my grill/cowl and i used some of this unactivated primer/sealer on the underside for a sealer and seems to work really well but of course dries slow
my bodyshop buddies didnt have a answer but admitted using old primer sealer on undersides of things and not having problems with it either.
