It truly is the best grease I've ever used. I buy the liquid bottle. After shooting 200 rounds at the range with my Glock 30SF all lubed up with it, all I had to do was wipe off the carbon residue all over the gun. It took about 10 minutes. The gun came clean with NO cleaner! Just a microfiber cloth. Cleaned the barrel with Breakfree CLP. Reapplied XF-7 to frame, barrel, slide, and recoil spring. Let it dry for 15 minutes. Put the gun back together and it's ready for more! Buy some! You won't regret it!
