Other products that didn't make the list are Tectyl 900 and Pro Lube II. There may be more.
I found 12.5 oz. spray cans for $9.43, and quart cans for $20.40, but no small bottles/tubes. Except . . .
A web site called Sharp Shoot-R has a product called "Maxx" that claims to meet MIL-PRF-32033. An 8 oz. plastic bottle for $12.00.
Any recommendations for a current commercial substitute that can be purchased locally, preferably in small quantities?
