Should I get Adam’s polishes foam cannon or a cheaper one on Amazon? So I just bought a newer truck and want to start taking better care of it. I heard Adam’s polishes products are good and wanted to try his car shampoo with a foam cannon. Do I need to buy his brands gun! Or is there cheaper ones that work just as good on Amazon? I have a pressure washer by the way, that’s what I want the cannon on. Thanks all
