I have seen this mentioned a couple times but it's real rare... Just curious who here actually uses 40W motor oil or whatever other W motor oil you prefer? Does it work the same as the hoppes or other lubricants? Does anybody add the Loctite copper C5-A lubricant to their guns? I noticed Glock uses it as a break in lubricant on the rails of the slide... Does anybody add more to it once it's gone or add it if the guns will sit for a long time? Also who has used the Weapon Shield brand lubrication oil on their guns and how well does it work?
