I must say. I followed some of the simplest instruction I found on the net provided by a guy that had reparked over 100 barrels and wow I couldn't be more happy with the results. The whole process took about 15 minutes and the results were astounding. I will have to see if I can find the rusty before pics. Had my buddy bead blast the barrel and fsp. I cleaned the parts with acetone this morning and rinsed them off. I will say u must hurry because in 5 minutes they will flash rust so hurry.
