Is cleaner wax such as meguires and mothers basically a substitute for a clay bar / wax multi step process? I understand it may not be as affective as a multi step process. I have some regular liquid turtle wax, how does that fit in there? Thinking of getting one of the above mentioned cleaner waxes for my pathfinder as it has some minor swirl marks in the white paint that my ice wax spray don't seem to do anything. I do remember great results using meguires cleaner wax on my Grand Prix.
