Thanx rdgietz, I purchased a used open gun just recently and the former owner recommended I use this product. I've ordered some GB grease and oil (its not that expensive) and was wondering how impressed other folks were with it. I have a supply of Miltec oil too which is supposed to have some supernatural properties. Its good oil but that's about it IMHO.
Anyhow, thanks for sharing your impression re the GB. We use a "stays in place" lubricant called Aqualube for some applications where I work. Its too thick for pistols but if the GB shares Aqualube's stay there characteristics that will be a plus for sure.
