How things change....lol. When I was a kid, I'd prime jigs made in home-made oak blocks with white house paint. Then they got some Herter's colors. Back then there was a spray kit called Krackle Kraze that was a two part thing. The under color was sprayed on and allowed to dry then the top color was applied and as it dried it would spider-web. It looked pretty cool and I'd imagine your granite coat would be similar.
There is never an end to what can be thought up to use on tackle. Toss in a little science and technology and you can have a field day. Good work SM!.
