Fixing mistakes in enclosure etching... Filler for bare aluminum?

[kvandekrol]

My first enclosure etch turned out really good overall, but there were a few places where the toner came off before the etch was finished, and as a result there are a few pits here and there. I'm wondering if anyone knows of a good way to fill these in convincingly? The ideal thing would be some sort of metal-colored epoxy, but all of the "metal fillers" I've found so far are dull gray and designed to be painted over. This will be a bare aluminum enclosure.

If all else fails I might just use regular clear epoxy so that it's at least flat, but I wanted to see if I had any other options before I do that.

Hi, I remember seeing filler for alloy car wheels that' silver and blends nicely when polished.
Might be worth a try?
