Good day all.
I believe my +4 bumpers are anodised aluminium but would appreciate comments. A magnet test proves they non-ferrous and the surface has a silvery appearance, which is now not as bright as it would have been. It looks like there is a coating of some kind, or maybe it is just the anodising losing its sheen.
I would like to lift the appearance so will try polishing, but does anybody have a suggestion for the type of polish? I have a few metal polishes which I can try.
The other option is to have them re-anodised or coated again.
Please help.
Neil
