You guys are going to have to forgive me for looking at this in a very logical way.
First, we are looking to find the most durable paint, but here's what I also think when it comes to durability.
Unless your going to drive it every day, run it down gravel roads, and drive it in the winter with salted roads, how durable does it have to get.
The factory painted my frame in 1952 and most of it is still there and they only painted it to provide coverage, basically.
I think the important part is good coverage, multiple coats, with what ever you choose.
I did a frame in the 70's and that cheap stuff is still there, holding up fine. Two primer and two top coats.
I've used POR-15 and Chassis Saver and think they are also very good, although it hasn't been 35 years down road yet.
The only down side to the high dollar stuff I know of is the inability to keep the paint. It always wants to harden up in the can once it is opened, which is a little depressing because the paints so costly, and it's a little more toxic to work with.
My last thought-- Unless your 20 years old and want to preserve your truck till your 80, or you want your great grandkids to be able to drive it someday, how durable does it HAVE to be ?
