I don't care for Remoil because it's very thin and seems to be as much a solvent as a lube.
I've come to appreciate lubes that are still there and not dried up when I take my gun out of the safe six months from now. Combination grease-oil preps work well.
Wilson's Ultima-Lube Universal is good stuff for us SIG users. Or any gun where you have a steel slide rubbing against an aluminum frame.
Also, TW25B is an excellent grease. I use it in the trigger mechanism. So does Sig Sauer. When you want to clean it, just blow it out with GunScrubber, dry with canned air, and relube with the syringe type applicator. Make up your own combo of grease and oil, if you like.
BreakFree works fine, and so does Mobil One synthetic--one quart will last near forever. Great for AR's, too.
All the lubes work, but some last longer than others. And I'm a firm believer in GREASE for aluminum frame rails.
Just my thoughts on the matter.
