What Paladin said. I have been using it for some time as a rust preventative on my XD and other semi-auto slides. It's excellent. I think I got my last bottle from Brownells. Thank you Paladin for pointing out the errors in that previous post (snake-eater). It's NOT like WD40 and it's highly recommended as a rust preventative for all metal surfaces including firearms.Paladin said:If you do a search, you'll find some previous posts by me on Boeshield T-9. This stuff is the ultimate for preventing rust! It was first invented by Boeing Aircraft to prevent rust on their planes. It is now widely used in many industries. I use it not only on my guns but also on the cast iron and carbon steel surfaces of the power tools in my garage. After three years, I've had no rust on anything I applied it to.
It has been tested by several reputable publications in the woodworking industry for just that purpose. It is consistently found to be the best product. One application prevents rust on all my tools in the hot, humid environment of Florida for as much as ten months.
Contrary to the previous poster's unfounded speculations, while it is a spray on metal protectant it dries completely in a few minutes. There is no way it can contaminate ammo or anything else after it has dried. Simply spray it on and wipe it off with a paper towel after a few minutes. Then let it dry completely for the next 20 minutes or so. There is no oily residue. You don't have to worry again until you remove it with a solvent or six months is up.
It costs about $12 for a large aerosol can. That will last you at least five years if you only used it on your XD. The problem is that once you find out how good this stuff is, you'll use it on all steel and cast iron surfaces that you want to protect.
