Need opinions on anti-rust paint (POR15, Rust Bullet, etc)

The new POR-15 has UV inhibitors, so it doesn't turn milky from sun exposure. I really like the stuff. One trick that works is to put 3 layers of wax paper over the top before you pound the lid back on. When you open it again, the bottom layer will form a skin which can easily be cut off with a razor blade. Wear gloves, eye protection, and old clothes!
