I'm going to give that Rust oleum undercoating a shot and see how long it holds up. It comes in the spray can.
Ya, I am going to go the same route. I was thinking Herculiner but undercoat maybe a better solution. I painted under one fender with black rustoleum rust proofer paint and it looks great. I don't like the sound of trapping dirt and water so undercoat it is.....
If u use ur jeep offroad I would use por-15. Its the best. It gets harder as it gets wet, not breakdown like others
Stuff is like iron once painted on.
