Bluemagic Metal Polish Cream 7 ozBluemagic metal polish cream is essentially Brasso dyed blue with more abrasive content. It contains ammonia and will react with aluminum and stainless steel by developing a black oxide layer that is buffed off. It also creates a noxious gas as a result of this reaction, so I highly recommend wearing a respirator or working in a well ventilated area.The Bluemagic will not fix scratches or pitting. It will give brushed stainless a shinier luster, and it will rejuvenate polished stainless steel surfaces and chromed surfaces. I bought it mainly for my exhaust pipe tips on my cars and motorcycle. On one particular car, which has a direct injection turbocharged engine, the tips will become coated with a thick layer of soot within a few minutes of driving. This is a common problem with direct injected engines. Look at any Audi car made within the last 10 years and their exhaust tips will be coated with black soot. This is not the result of using 93 octane fuel, but rather a combustion byproduct of a direct injected engine.More and more vehicle OEMs are switching to direct fuel injection for better fuel economy, more horsepower, and better fuel metering. This means we get better engine performance, but the exhaust tips start to look nasty after a few miles. This is where Bluemagic comes in. I was able to get rid of some of the soot using regular polishing compound. However, Bluemagic got rid of all the hard soot deposits. Unfortunately, it couldn't do anything for the pitted surfaces. But it was able to get the chromed mirror-like surfaces looking better than new.On my other car, the tips just looked a little worse for wear but the mirror polished T304 tips were still in good shape. The Bluemagic shined it right up. On my motorcycle, the Termignoni tips are just brushed stainless steel but the Bluemagic made it shinier and brighter.I would recommend wearing gloves, as the Stoddard solvent smell will dig into your fingers. The black oxide residue also gets everywhere on your hands and buffing rags, so a well-ventilated workspace is mandatory.I would also recommend keeping that foam gasket in place when you remove the cap. Just lift it halfway and tear the clear seal. The gasket will help prevent it from drying out.Overall: 5/5 stars, very inexpensive solution to dirty exhaust tips and metal surfaces.
