Looking For Insight on Emulsion Sprays for Axle Prep

I personally have not. However, I would suggest (from experience mind you) to try and perfect the processes available here on the forum first, and then once you make the top 5 or 10 on the list, then experiment with other things, as the "PROS" are quite fast! I can also say that I know for a fact of 3 fellers that have literally spent thousands of dollars on crap that didnt work...FWIW.
