My Fenix L1D set me back $50, so I had my name engraved on it in case it should be lost or stolen. I thought this was OK, because aluminium doesn't rust (it corrodes, yes, but not as badly as iron or steel), the exposed surface area is so small and I thought the anodization was for decorative purposes mainly. However, I am now worried that I may have made a mistake; that there are consequences I did not know of. If so, how can I fix this? What if I painted over the letters with a fine brush? What sort of paint should I use?
