I have'nt seen any B-12 in the parts store I work at and at neighboring parts store. Then low and behold burried in the back room I found 7 bottles of B-12 Chemtool. I've read this B-12 is stronger then seafoam and a fraction of the cost (2.xx vs. 5.44). I want to make sure this is the right B-12 evey one raves about.
