I had used Maas for many years. Recently I had to replace this and decided to go with Simichrome this time. I think they are similar. I bought both online. I use Renaissance Wax after polishing to delay tarnishing and preserve . I have also used Johnson's Paste Wax. This is all after I have used buffing wheels and buffing compound (another thread topic?).
I just used Blue Magic on a 1000 day base that was black. I think I worked less than I would have with Maas, and it's affordable and a half mile up the road! I'm sold. Flitz is also half mile up the road, if I ever decide to try it.
Whenever the old lacquer has really gone south, I have to resort to other chemicals to cut through it. I've been using a gel-based paint stripper...that way I can control where it goes and keep it away from the plastic in the base or whatever is sandwiched between the brass. It takes some time, and I usually let it sit for at least a couple of hours...sometimes I have to go a second time. Anyway, this helps to reduce the amount of elbow grease needed with the paste/polish.
