My wheels are oldies, I got them back in the 70s in an oxidized and neglected condition for cheap. The Brand is Appliance, the style is called slot mags, they go nice on my 67 Mustang fastback. I taught myself how to polish aluminum on those wheels, used sandpaper and then buffs on an electric motor and sticks of buffing compound to get back to a mirror finish. Later on I got a set of 73 Mustang factory mags which looked very similar to the Appliance mags and I polished up a pair of those and put them on the front of the car, the offset worked out better.
I have several other pieces of polished aluminum on the car, engine brackets and stuff and am always looking for new aluminum polishes. I've tried a number of metal polishes, so far I'm inpressed with the Adams 2 part system, it brings out a nice bright shine. I've never tried waxing or sealing my wheels, always just relied on the polish to protect them. My car stays garaged most of the time so the wheels don't see a lot of weather.
