I'm being asked to gold fill a logo engraved into the lid of wood box. I've never found a gold paint that looks good, and paint filling wood is usually just asking for trouble, so I don't think I want to go there...

You guys talk about gold foil- I've never used the stuff. I see that it's adhesive backed and I assume laserable. Not sure it's do-able to after-fill wood engraving. Is it? If so, is it a vector-cut-afterward thing, push in what you need in and weed off the rest?
