I've used the POR15 paint and that stuff is good. I foam brushed it on frame after proper prepping (I'm down south but still want protection). Toxic smell even with mask though.

Speaking of up high, how do you all stop the roof drip rail rust? I keep my truck dry, but occasionally it's going to get wet, or damp. Does the infamous rust along the roof line start inside and rust out or is it from water resting on the drip rail? Is it enough just to dry the exterior whenever it gets wet?
