Where could we possibly get that rusty colored lube that is at the rear inner slide of our glocks? I just noticed that mine has already faded away. Or will you guys recommend that we can replace it with, maybe grease?
It's an anti-seize compound. It's available with industrial suppliers. Don't bother using it though. A small can could cost you about P2,000.00 Use good quality oil on the parts that need to be lubed. There's a section on properly lubricating a Glock at www.glockmeister.com.
For my Para 40, I use Castrol synthetic "anti-friction" racing oil. Not so viscous though, unlike the Silicon oil, but find it excellent especially with my S/S slide continuously racking the frame. It's P130/liter.
