Ryan- On the Jag, I've used Malm's liquid (that was back in the mid '80s), Meg's #16, P21S, Trade Secret, and Souveran. Probably used the Souveran more than any other. Some of the chrome that's hard to detail (as in, have to remove it from the car to get at it all) gets AIO/SG x many/wax.
I do the same on other cars' chrome, but as I've had the Jag the longest and it's been subjected to all kinds of conditions (and it has plenty of chrome), it seemed like the best example I could present.
