3M Marine Aluminum Restorer and Polish, 09020, 18 oz, for Marine Detailing, Remove Heavy Oxidation and Chalking, 1 Tube

On my trailers aluminum windows this stuff worked so great on the chalky areas, they actually came out shining like a mirror! This stuff doesn't work on major pitting. In fact there is pitting in most areas of my windows (from exposure to salty sea air) but even getting the non-pitted areas shiny make everything look better especially when you take a few steps back. The pitting will look like corrosion (in case you don't know - the pitting is the rough parts like there is something that needs to be scraped off, the smoother "chalky white" areas will come out shiny) It did help the pitted areas some but took more buffing. Be prepared to use up ALOT of soft cloths, the junk that comes off is black.It doesn't smell that bad so you can use it indoors in my opinion and my cloths washed for reuse (stains weren't totally gone but that is ok). You will be using a good amount of "elbow grease" it takes time to get the results even - especially since my windows have screws through the metal every few inches and it's harder to get it buffed in those areas. But this is definately a good product.

It was an expensive purchase so it needed to perform. It did. It is a pro level product and delivers excellent results. You do not need much product so the tub will last well.

I use this to clean my pontoons every year and works great.

This is one of the best aluminum polishes on the market. Use to to shine my sliding door tracks to a mirror finish with a buffing wheel

My husband usedthis product on his boat and has been trying for years to find a product that worked. This product worked perfectly and with a little elbow grease, he was very happy with the results. You will definitely buy it again if needed.

This product is more for very light duty aluminum polishing and for that it works well but if your planning to restore your aluminum to a bright polished luster then you need rouge and the correct buffing wheels to go with it. The buffing wheels range from rough to fine polishing with corresponding rouge. Zephyr makes a complete line of buffing wheels and rouge and you can find everything you need on Amazon. Note: I have no affiliation with any of these products or vendor nor am I into retail sales. Cheers

This product is great! I use it to restore faucets in the bathrooms I clean. It also leaves a protective coating so you don’t have to keep up with the maintenance of scrubbing.

This isn't for seriously stained or corroded aluminum. There are other product for that. But if the metal is reasonably clean and smooth, this does a nice job of cleaning and polishing. But don't expect miracles - there's no substitute for hard work and technique. Once the metal is reasonably clean this will actually polish it and make it shine. But it won't bring back something heavily oxidized. That's not it's job.
