I tried the Zipwax car wash stuff. I didn't expect it to work very well, but holy crap, the water just beads right off after the final rinse. Pretty impressed. After Dupont car wash soap with teflon, that's the best car wash soap I've ever used. I know people will say, "what about Maguiar's and Mother's?" That stuff works really well also, but for where I live (lots and lots of bugs,grasshoppers, etc...) the Dupont shit works great at removing them without using chemicals like Goo-Gone, Turtle Wax bug and tar remover,etc... Sorrry about going off topic, No, I haven't used the Mr. Clean Autodry.
