On that factory bait, I would do the top like CCM Jr did for the cold steel color. Just add a drop of CCM X2 blue and you will be good.
The custom one is just like a Sexy Shad to me but add a little gold in the bottom. Either flake or smoke gold pearl. Or, like Jason said, that sand recipe would be killer too. Leave the black flake out though I think.
Should be a cool color. I have been wanting to do the Sexy Red Shad for months now!!!!!
