Color change for plastic swim baits

I am one of those folks sales companies love. Send me an ad for something new and different, I'll try a few some of the time. Most of the time they end up in a box on a shelf in the garage(never to be seen again) but sometimes they actually turn out to be something the fish like but haven't seen.

I just got in some silicone minnows from across the Pacific that look like they have a ton of potential, just not color options I would have preferred. Now I'm looking into doing some color change games and was wondering what has worked for you folks. I've looked at Spike-it dip and markers but want to know if there are others that might work better with a wider color selection and that will stay somewhat colorfast after use? I'm starting with clear smoke with some flake.

I use CS Coatings UV Blast Worm dye...the colors are Fantastic, and the only plastic that it won't dye well is the Z-Man material. It's turns my clear and white Keitech baits into AMAZING colors.
You can get it a www.jansnetcraft.com among other online retailers...it's right at 5 dollars a bottle!
