I'm going to be getting some mild salt damage fixed on this truck. It spent some time in Maine yet thankfully the exposure looks to be pretty light. The main thing is that the truck never had any splash guards or flaps on it and so the very bottoms of the front fenders have been pelted pretty bad. The rest of the underbody and frame look OK but they have some spots where rust has flaked the paint somewhat and some of the cast parts are showing a little. My question is this... ... . What have you guys used that works? I've looked at Eastwood Rust Encapsulator, Rust Bullet and Por-15. Any other ideas?
