Hey Bobo, the jig looks good bud. Could you describe what you used/did to get the look you ended up with please. Also, IDK for sure what you're wanting when you say "Marbling". If what you're after is the look some got when using a Vein base coat & a Candy color as a top coat, crappiehappy has that technique down pat! I followed Heath's process to get this...

then there's this Vein coating with just a clear top coat...

I'm pretty sure your jig will catch fish!
