My aluminum wheels on my 1996 4-wdrive have been exposed to every bad corrosive process the elements can come up with, acid raid and road salt just to mention a couple ... a radio in my home would fair much better; And, the rims still look excellent! I love it when someone mentions a non-issue ... however, I do have some old military equipment in the basement which is aluminum cased. It would have to be polished and repainted ... was made in the 1940's. Regards, JS |

You need to use more expensive alloys to beat the longevity of plastic in the real world.- Hide quoted text - - Show quoted text - Aluminum corrodes ,like almost any other metal,when exposed to acid rain/salwater. My 50 year-old R-648 /ARR41 (was forced to sell it at one point) was kept indoors and was absolutely immaculate cosmetically . It didn't look like an alloy or anodized at all. |
