I know this post is 7 years old but I recently tried this jewelers rouge formula and all I can say is it far exceeds anything I've ever used before! Total cost was about $15 bucks and it made enough for a year worth of polishing. The only thing I did different is instead of scraping the bar with a knife I used a cheese grater and that took the bar down to a pulp in just minutes. I polished the aluminum return hose for the A/C and it now looks like factory anodized aluminum. I then got crazy and polished my send and return lines off the automatic transmission. Heck they were out and now they are like mirrors! I then did the stainless moldings on my El Camino bed with 0000 steel wool and followed up with cotton and they look better than factory. This stuff is like magic.
