Two industrial-sized cans for $16! You have to ask for the “Google Offer.”
This stuff has been a lifesaver two years in a row now. I leave the parts to my steel-pipe shooting bench outside all year, and despite being in sunny California, inevitably a few of them end up rusted together. The weekend before Boomershoot I douse ’em with Kroil, and within 15 minutes I’m able to separate most of the joints by hand, no tools. Great stuff.
