I only chamber about 4 barrels a year, I just ran out of Moly D, I have some Pump Spray Accu-Lube,Tap Free ,Thick tap oil, Tap Matic fluid, Trim-sol, trany fluid. Getting ready to buy some more Moly D because it has always worked well for me. Is that my best option considering the other oils I have.?? All barrels are SS. I think a pint of Moly would last me a long time and I can get that for approx $20.00.
