Thanks for the replies guys.

I'm using Klasse AIO polish after clay bar, and then two coats of Klasse sealant and then usually a carnauba wax to top it all off for my big "make it perfect" details and then I've been using Meguiars Gold Class for my weekly wash followed by Meguiars spray wax while I dry. I thought the same thing, get enough coating on it and nothing would stick but it does.

I did indeed mean agitation and not scrubbing.

I'll try my new setup next week with the Ultima and report back but I think I might also want to try the foam cannon with my new Mr. Pink. We'll see.
