Razor Edge, 2 yrs old.
Was applying Carnauba, now Ceramic. There is a difference, but it isn't some sort of miracle potion. But it is better.
$13 top pkg: Bug pass, Hi Ph, hp rinse, low ph 3x Foam, hp rinse, Ceramic (via RainBar) SFR & exit through dryers.
Top pkg is 76%. We are a very busy site.
Im gonna try KR Kleen Pak hyper concentrated Ceramic Wave. Only $182 & dilutes 600/1.!! If this stuff works, Im switching for sure. McClean Ceramic is $600 & $700 for 5gal.!!!!
