May I ask, (and I understand this thread may assume the same sort of context as oil and tyres, i.e. contentious), what do owners of metallic paint finishes (lacquered coating) use for a best finish / protection?
I was told many years ago not to confuse polishing with waxing. My understanding is that best practice is to use say a clay bar and your chosen polish to get the paint/lacquer free from surface oxidation, swirl marks etc. Then it's waxing which produces that high gloss you are seeking. My Roadster is a "solid" colour so I don't have that to consider, but I keep the paintwork on my metallic blue Fiat Spider (with clearcoat) waxed -- you can see the effect with water beading. There are lots of detailing sites on the Internet which cover these processes in depth.
