Ahhh ..... sorry but I polish, I j-ewel with a finishing polish, (I wipe with alcohol/water mix if polish has fillers) and then protect. No need for paintcleaner. The two I listed above are not rather chalky but havent used in awhile also.
What about Klasse AIO. It is a chemical cleaner. You can use just about any sealant or wax over it, and very good at paint cleaning and prep ?? You can use it by hand and/or with PC ??
I will ask around on Ultimate Cleanser specifically, but remember that comments always leaned to mediocre on everything more than the sealant, and gloss spray in the Four Starr line.
