Ok I have to throw another wrench in this cause you can never have to many mechanics wrenching on a dead horse...
Since budget and durability are recurring factors and present in this thread I offer this as fat to chew.
Ever consider that rustoleum and duppedlicolor are considered near the lower fifth of the quality paint ladder on Painter and Body work forums?
In the beginning...When I was at this very point (Selecting paint) I chose what was available and affordable for my frame. It took about one can to realize I was going to go bankrupt buying cans of spray paint so I spent 20 buck for a cheap sprayer and another $30 on a couple qts of rustoleum. I was happy but I was only concerned with coverage and price.
When it came time to work on the body I, as a novice started lurking on paint forums and spent hours searching for the magic formula of durability, affordable price and a positive industry reputation. I figured out who the guys were that posted the most reasonable answers and started 'weighting' their ideas on the balance beam of reason. I even went so far as to google the names of some of those guys to find other forums they might be posting on. In the end it lead me to Southern Polyurethanes Inc. For $180.00 I get 2 spray-able gals of epoxy primer. Thats $22.50 a quart folks... in White Grey or Black. Its all I'm using in my body work now. Under and over any filler I may need. I'm blocking and sealing with it as well. No need for guide coat as the sheen shows up great whether dry or wet sanding and when I'm ready for color I'll use it as sealer just before it. I've brushed it on in spots that were pitted and even filled one small pin hole in the back of the cab with successive applications.
All that plus the peace of mind knowing I am using one product from metal to color coat so compatibility is not a concern.
And they ship right to your door if you don't have a local distributor (which your not likely to have)
Go ahead, check em out...
I dare ya....
