mothers billet metal polish, it is a paste in like a small 2 oz glass jar. $10 vs the $5 for the larger tubs of metal polishes, but you get what you pay for. Auto stores have started carrying it, I had to buy it mail order from mothers last year. It's fairly new, but most people who use it never have anything bad to say about it. Don't use it on chrome, it's a metal polish.
you can buy noxon at most food supermarkets. Has strong ammonia smell to it from what I remember, and wasn't all that great.
I'm a big fan of never-dull too. It does work good, it's a favorite among boaters and does a good job on stainless and aluminum corroded by salt water among many other things. I always figured eagle one wadding was the same, but maybe the never-dull has a higher quality oil in it.
