Hydro Blue question

[dennis hiip]

As I understand, Hydro Blue will bond best on bare paint, but I'm thinking of trying it on a well maintained car. Rather than clay, I was thinking of using P21 paint cleaner to remove contamination and provide slight correction. Will P21s hamper bonding? Help bonding since surface is clean?

The surface must be free of any protection wax, sealant ect

I've used hydro blue and Hydro2 on many vehicles that didn't have "bare paint" and they worked fine. Now does it last as long? No, but it's so quick and easy to apply it doesn't mater too much IMO.
