A friend of mine is looking for some way to remove the anodizing from his GM coach. About half of it is gone already anyway. He intends to polish it out and maintain it that way. Does anyone know of a chemical process to do this? Thanks | ||

Gary ..... HAR de HAR HAR! (seriously now) One said: "Removing anodizing: teaspoon of drano to one quart water" There's a ton out there. Just type: "Removing anodizing" in the Google search engine and go fir it... (who said to burn it off?) | ||

Two Dogs I think what you're talking about is called Roloc and is made by 3M. http://www.3m.com/market/electrical/elpd/mro/ Click on "abrasives" on the left hand side of the page. When this page loads, look on the right hand side of this page and click on "Roloc". Glenn | ||

Years ago I bought a Kenworth truck with grungy aluminium wheels, spent about 3 hard working days polishing them up to a a very nice shine, Turned out I would have to do it about once a month. needless to say, NO WAY | ||

Isn't it the anodizing that's kept that aluminum from decaying over all these years? | ||

John has it right! There was a stretched Senicruiser with stainless in place of the aluminum at Bussin' 2004. He had the smart way to shiny GM's The anodising is a chemical "hardfacing" treatment of the pure aluminum that covers the alloyed aluminum. Without the Alclad, the alloy readily corrodes. Taking off the anodizing removes the Alclad. It's like removing the makeup off a 4 drink "ten" rated woman. You won't be happy with the results. Onward and Upward Marc Bourget | ||

John, that's the problem. However, if a person has already polished some aluminum and wants to keep it shiny, several coats of penetrol seems to work on salt water skiffs and the handrails on our boat. There is a fellow here who builds new skiffs that told me about this. He said that after several coats on the aluminum piece the windshield was installed in, there was no change in appearance after seven years. I noticed that penetrol adds a slight yellow cast to the aluminum, but it would depend on the person looking at it to say if it was objectionable. Penetrol is normally added to paints and varnishes to improve flow characteristics and can be found at lumberyards. We really like it for this, as well. For what it's worth.

There was a three page article in the Mar-Apr 2002 issue of The Coach-Builder's Bulletin on how to remove the anodizing (oven spray), how to polish the aluminum, and how to maintain it once you do. All back issues are available and listed here on BNO. | ||

Why can't you clear coat the aluminum after removing the anodizing? Wouldn't that keep it at least to the mill finish. Our aluminum looks like crap due to the dead anodizing and the hit-n-miss silver spray paint (right over the dead bugs on the front) but sure shines up pretty with a 3M pad and an awful lot of elbow grease... far too much for lazy me. I have a small piece of siding sitting in the shed (out of the weather) that is still shiny after 2 years and the spot on the bus is still pretty shiny after 2 years in the weather. Thought the tinted clear coat that POR15 sells would be the way to go for us (deep red paint above what's left of the fluted aluminum and then red tinted clear coat the entire thing. Supposed to paint right over chrome, etc. I kinda dislike the shiny chrome/aluminum look anyway. But that's my personal taste. | ||

Will clearcoat stick to Aluminum? In the past when we've painted aluminum, we've had to "Pickle" it first, which as I remember did no favors to the shine. Gary | ||

Do they even make it anymore? I'm not sure they do, it didn't even come into the discussion when we were deciding paint for the MG. Gary | ||
