I just purchased a 1987 300D and am very happy about it! The burgundy paint job on it looks amazing to me, but a guy who cleans and polishes cars for my neighbor (he has a shop and a mobile business), says there's a need to remove oxidation before polishing and waxing. What he wants to do is a machine buff before waxing. He says that using clay would not be appropriate because of the oxidation on my car, and that clays can sometimes stain the finish.

Another detailing place that I called uses clay (I don't know if they plan on machine buffing first) and uses three coats of wax, finishing with a hard carnauba wax.

Lastly, another detailing place that works on prestigious cars uses clay to polish and then applies the trademark Polycoat material, then a coat of wax, and then another coat of Polycoat?

Any thoughts as to what I should do?

Thanks,
