Apparently not popular with the antique or show car crowd where cost isn't an issue if the results are significantly improved. I have not seen it offered by those speciality vendors (I get a lot of their catalogs & publications) and haven't seen a write-up in the antique car publications. That's not to say there hasn't been any, but see the Meguiars & 3M topics this forum. They are the two dominant brands. Some do as much harm as good (ArmorAll) where discoloration and chalking become noticeable when not kept fresh. They may attract dirt and contamination as well, especially if they don't 'dry.'
