Our '68 mustang is showing a slowly progressing, whitish corrosion on the aluminum sill plates and the base of the shifter cover. Has anyone else experienced this and found a way to stop it?
Aluminum corrodes just like steel once whatever protective coating it has wears off....the parts are cheap enough to replace, but if you are dead set on keeping the originals, you can strip and clear-anodize them. The shifter base though I believe is actually chrome plated cast aluminum though, if its like the taillight bezels
Aluminum and zinc alloys corrode like that when they are constantly damp and the protective coating is gone. I live on a boat and it doesn't get that bad...you must have a lot of moisture in your carpet.
