Greetings my12bps, and welcome aboard.
I knew a couple of guys who got some gold paint stuff (I don't know the brand) to put in the engraving of their Citories. The stuff looked awful from the beginning and didn't get any better with age. IIRC, the problem was the stuff always seemed to have a ragged look the the edges. Where the original engraving had a clean edge the paint didn't follow it very well. Nobody is going to think your gun has gold filled engraving, they'll know it's just cheap paint.
