I recently used Rust Bullet around the roof drip rail on my '65. The rail is a very poor design where water easily accumulates and sits.
I wanted something that would really adhere and provide a strong barrier. After taking it down to bare metal, I applied the R.B. It definitely has good adhesion. I dripped some on my vent window and it's still there. Got a bit on my hands and took a while to come off.
I applied it with a brush in the drip rail and ended up with some air bubbles in some areas that I had to go back and fix. I think spraying this product would be better and help to eliminate that sort of thing.
Only time will tell if it was worth the money and that it actually provides a good barrier.
Overall I was satisfied with the product during application.
