Rust Bullet

I've used it on my 67 fastback barracuda, I liked it. It has been a couple of years since I used it but what I do remember is that if you are going to be spraying it, your going to need a huge tip for your gun. I think I shot it with a 2.2 or something like that my buddy had. I ended up only spraying the areas that would be visible later and switching to brushing it on the rest of the interior and trunk. For the hassle, just brush it all on unless your going to be on an exposed painted surface. It actually flows out pretty even. I can't speak to how durable it is since its still on the same jackstands in the same spot in the shop that it was 2 years ago when I did it. I can tell you that it's hard as hell when fully cured. As far as the amount, on their website you could order 4 quarts in a packaged deal for the same cost as a one gallon bucket. I went that route and did 2 coats on the entire inside of the car, the inside of the doors, the underside of the trunk lid, and the engine bay. I have one unopened quart left right now, I'm sure that I will find a place to use it at some point
