You'd be better off using Crisco or Lard before Rem Oil. I'm being serious here. RemOil is mineral spirits. That's it. It provides almost no lubrication at all and certainly no protection against corrosion. It's too thin. But don't take my word for it. You don't know me. Read the below link. If it makes sense to you like it does most people than follow it.
Wow, I see a lot of people shooting blanks on here... FrogLube is the real deal, folks! Check it out for yourself, buy a $8-10 T&E kit... it should treat 3/4 guns. But you don't have to take my word for it... "Reading Rainbow"! Lol ;-p
