3M Marine Aluminum Restorer & Polish (09020) – For Boats and RVs – 18 Ounces 3M Marine Aluminum Restorer and Polish, 09020, 18 oz

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.

On the aluminum I polished, it worked OK. Going to try it on a very dirty pontoon boat in the spring.

What a great polish 👌

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.

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.
