z-max,anyone ever try it??

I saw what Slick50 does. Glass like coating on the metal. Nothing short of a steel wire brush would take it off of lifters and such. I can't say if its good or bad. Just not for me. I think differnt from most folks and apply pretzel logic too often. An example... If the drugs we put in our bodys to help us live better or longer ALL have their side effects, shouldn't those additives for engines also have side effects ?
