Willie, sorry to hear of your loss. Glad you were able to save your machine shop tooling from being a total loss. Best luck man.
Hot water and soap. Bore Butter, CLP and Lucas Gun Oil. A bit of Gorilla Grease on threaded parts. Works well for me. Ballistol, never tried it, but due to everyone loving it, think I will order some. As to WD40, it has its place I suppose. I banned the guys from using it in the shop as it was misused, in a maintenance shop I find it attracts/holds dust and isn't a good lubricant for what we do. Never tried it on a gun. Some people love it. I do not. Just my .02
