im in the middle of sand blasting my car... I have a lot of questions...i used rustoleum auto primer in the rattle can to prime a panel at a time because i don't think i would like to use a spray gun and clean it every time. The car is stripped down to bare metal as you can see above...my question is if it will ok to use rustoleum as a base coat of primer and then use my "good" primer that i already have (http://www.paintforcars.com/primer_non_sanding.html) as a second coat of primer and good paint/clear on top of that...will that work??
if i was you...spending all that time blasting...i'd suck it up and spray it with a gun because i know the quality will be way better, even though the 20min gun cleaning after sucks. spend time now, be happier later.
You have to careful with the rattle can stuff, some "real" car paints don't react well with them. With bare metal, I think you'd be best to use some sort of self etching, epoxy primer.
Not only are you dealing with compatibility with future products you also need to find out the lifespan on that primer. All primers have a time span until it lets moisture through. (so my painter told me) I was under time constraints on mine due to that. Some are really short and other like epoxy primer are at the other end of the scale.
