I too prefer ZeroRust over POR-15. I've used both but the POR-15 is just too nasty to deal with.

However, I don't agree with the remarks that you shouldn't use it if your headed to the car show. I painted my frame with POR-15 (before I knew better) and I painted the bottom of the cab, the bottom of the bed, and the engine compartment with ZeroRust. And I have taken home many trophy\'s from the car shows I've entered. Oh sure, if you plan on taking it to Pebble Beach or some other Concours d'Elegance show, then brushing on a coat of ZeroRust isn't going to get it. But for the local car shows like most of us go to it will do just fine.
