I "rubberized" a 1997 Dodge 3500 with 3M 5200... then oversprayed her with 5-6 cans of flat black $0.97 Walmart spray paint.
$5k Cummins... Mechanically BRILLIANT! Cosmetically FUBAR.
Mountain Truck... PURE WORK.
Tough stuff (i.e. "throw rocks at it"... tough stuff)
5 years now... wearing like iron.
