Stop in for a cup of coffee

What do you guys use for chrome polish? Now that I have something worth using it on. Best all around metal polish I found is Mother's. Did a little with it yesterday. Lightened up a few scratches. Looking for best kind for scratch removal, and best for shine. I think the one we used at Harley was called Simchrome. Made light scratches disappear in seconds on new stuff. But don't know what it would do for an old piece.
I always ended back up with the Mother's chrome polish on my bikes. I have never really found anything that did particularly well with scratches.
