The stuff just works. All my local friends hollerin POR15 but I've used it. It's messy as heck, gets everywhere.....on your balls, in your buttcrack.....I mean everywhere. It's worse than anti-seize. Plus it's expensive.......and THEN it requires an expensive compatible top coat because it's sensitive to ultra violet light. No, I'm stickin with Rustoleum. It's badass.
