Not only do I BEG to DIFFER - I have the experience and reviews to back it up!I've used other industrial 'no-rust' paints before... They're pretty much all the same.
Ah yes - then we agree on the paint-types all being the same!What I meant was the 'paint-type' no rust paints like Rustoleum, XO Rust and such are just that - paints. The evaporating solvents leave microscopic pores in the coating.
Epoxy paints are different since there is actually a chemical reaction that causes the cure.
To be honest, the only time we've tried POR-15 was a brush-paint job on an engine, and it was a PITA to get a consistent coverage - it was like painting with molasses - and that was after we had thinned it by the maximum 5% with the proper reducer.
