Had a "ziz wheel" blow up on a grinder today. I had a welding hood on with the clear lens in while I was cutting. I turned it off, but it slipped out of my hand while it was rpming down and hit the ground and blew up. ALWAYS protect your eyes!!! It was a brand new wheel too.
Recently I was washing my wife's Odyssey and I thought to try Comet with a wet blue paper shop towel. It scrubbed off the oxidation pretty well. The next step was a rub down (easy ODT) with NuFinish and buff till dry. They turned out really well.
Now mind you this cleaned up the oxidation on...
Used some on a gas tank on an 85 Ford pickup about 20 years ago. It would leak gas if filled up. I had to drop tank a little and the leak was under the strap. I gobbed it on and it never leaked again. Worked great.
