I'm new to the forum and detailing and have clay barred my vehicles and have used Wolfgang sealant on them. I'd like to add a carnauba wax and have some ordered from Autogeek. My question is can the carnauba shine be improved by buffing with a polishing bonnet after I've removed the wax residue with a microfiber towel? I'm using a Dewalt variable speed polisher.
No. Once you've buffed off the wax, the only thing you can possibly do to it by polishing or buffing it even further, is removing it completely from the paint surface. Which you obviously don't want to.
A wax works by filling the tiniest little scratches in the paint, and through this making the latter perfectly smooth, or at least smoother, than it would be otherwise. By - so to say - buffing the wax off after application, you're merely removing the excess wax, that's not need to fill the tiny crevices, and would just lay on the top of the already level paint. So, by applying the wax and the buffing it off, you're essentially just making the surface perfectly even. But obviously once you've done that, you can achieve no improvement with even more buffing - because the surface just won't be more level (at least not through the buffing of the wax), than it is already.
In order to enhance the appearance of your car beyond what you could achieve through waxing, you would have to do a paint correction on it (ie. remove the visible scratches by using a compound and machine polisher), polish it, and possibly coat it (with a ceramic coating). Of course that's just for the paint, because other parts of the car, like windows, plastic parts, rubber seals, etc. can be improved by other means. They also should be, because even with perfect paint, but untreated plastics, rubbers, and windows, your car just won't look "right", or at least not as clean and shiny as it could.
