Pretty good stuff but a little messy
Good stuff but a little messy when used with high speed polishing felt wheels. The soft compound (Dremel No. 421) flies off the wheel and get's on everything nearby including your cloths. So wear old cloths when working with this stuff.
It also will dry out over several years even if you keep the plastic rubber lid on the container. So you will have to either figure out what type of solvent they used to soften it up or buy a new one.
I just used it to polish up some old rusted bits that were in my tool box and got a little rust and corrosion on them making it hard to read the size or number on the tool bits. It did a pretty good job of cleaning up the rust and corrosion so I could see the sizes that are stamped into the metal of the bits.

Great for cleaning oxidation off of metal car trim
I received this compound with the Dremel Cleaning and Polishing kit. I used this along with the Bristle Brush bit to remove heavy oxidation off of the metal trim on my 10 year old Volkswagen. It works great! I tried numerous other metal polishers from the big box and auto parts stores and even some household remedies like vinegar, lemon juice and baking soda. Nothing cleaned it like new compared to this compound! While it is a bit messy when polishing at high speeds it is well worth the couple of minutes of clean up time for such amazing results!

Overcome the negatives
I agree with the other reviewers that the product does dry out and can be messy when using the high speed Dremel tool with the felt polishing wheels. However, I had 60 brass card catalog handles to clean that were very badly tarnished. I tried several different brass cleaning and polishing compounds but none worked very well. I had an old tube of the Dremel 421 compound that had hardened as stated in other reviews. I found that by dipping the spinning felt pad into the compound it would coat the pad and the compound worked very well on the brass with the exception that sometimes the hardened compound would break loose and fly out of the jar.
I used up that jar and bought a new one. The softer compound did fly out when I dipped the spinning felt pad into it and was very messy. After donning a pair of rubber gloves I dipped my finger into the compound and applied it to the brass handles with my compounded finger. Worked great. Took the heavy tarnish off and then I applied a lightweight metal polish to bring out the shine. My handles now reflect like a mirror. Best thing I have found to clean brass, even better than the so called brass cleaners,.

Use it fast!
It does everything it should, right out of the package, but the container needs to be upgraded. In that little plastic jar with that plastic cap- it just dries out too quickly! You reallly need a small air-tight bottle to transfer the contents into.
