rail

I shoot a Excaliber Exquinox and was wondering if you use rail lubrication, if so which brand, or not? I use the heavier string serving and have been using Scorpion Venom rail lube. I am torn as my serving seems to wear out fairly quickly and I have two buddies who have the same set up as me...

New in box, never fired Taurus Judge .45/.410 revolver. Purchased new from Vance's for $469.99. I'll sell this gun for $425.00.
