Cheering-up anodised (?) aluminium window frames...?

[MYStargazer]

I'll be taking my windows out shortly and fitting new seals.

The temptation to pop the aluminium on the polishing wheel and make it shine is almost overwhelming.

What would be the effect of this vis-a-vis corrosion?

Would the anodising be lost? Would they dull quickly?

Polishing will remove the anodising - its a hard coating that covers the aluminium, it can be coloured or clear (in this case clear)

If you do polish them you'd need to protect the alloy to stop it corroding - a clear lacquer will do this and still show the polishing (slightly diminished) but it will probably need re-doing quite regularly.

Of course anodisation will be lost. Why not consider re-anodising? It is quite inexpensive especially if you can't paint. Should you do so, marine work needs AA25 british standard grade.

I didn't know it could be re-anodised! I was thinking this was very much part of the production process.

Any idea as to very rough costs?
