FYI, I came across what I think is the best car wax I've ever seen. I've used darn near everything out there between my 55 Packard and 68 Cougar over the years, but this German stuff I never heard of before, by Klasse, is definitely the best I've personally seen. I tried some of their all-in-1 product (which is supposed to only be the 1st step before using their sealant glaze) on a Honda gas tank I'm sure hasn't been waxed in over 20 years, and just wiping the stuff off after application had that thing looking like it had been buffed to like new. Definitely shocked me because nothing else I've used could duplicate this sort of effect in a wipe on-wipe off fashion like this Klasse stuff.
Those looking for something to bring life back into old paint jobs might want to try this stuff. Cost: around $20 which isn't too bad
