Unless you find some one who has used the stuff, and has experienced it's performance, and decided to sell it (as I did in my shop), I doubt you'll find any parts stores selling it. The only price break you get on it is buying in larger quantities. I used to order it in 5 gallon cans and then relabeled old quart oil containers to sell it. It's hard to sell it UNLESS a customer has used it. Just before I closed my shop one of the other shops in the area gave it a try. The owner was impressed and wanted to start selling it too. So we started ordering it in 15 gallon drums and splitting it up. They say it's not for retail sale but we did it anyway. One thing you do want to watch is the SMELL!! If you get some on a hot manifold it will run you off!! They make quite a few different products which are I suspect are a variation on the original formula Kroil which is the best penetrating oil I have ever used. I use the formula which has graphite in it. Lubricates as well as penetrates. Do a google search and you'll find lots of different uses for it. They give a money back guaranty, can't ask much more than that! But hey,,, that's just ME!! Bruce Hevner
