DO NOT CLICK
Here's a little write up that TubeDude did on it a while back (it's on the float tubing board under "Best of the Best"): http://www.bigfishtackle.com/...?post=165396;#165396
Hope that helps you out a bit. I'm sure if you send a pm to him he'd help you out even more. Good luck.
Skunk happens when you fish with Mike!
BRING ON THE ICE, BABY!!!!!!!!!!!!
There are two ways to color plastics. One is to use a dye, like the one below:
This stuff penetrates and colors the plastic all the way through. You can color light colored plastics darker, but you can't color dark colors light. And, if you are using a color dye, the end result will often be different than the color of the dye. For example, if you try to color a chartreuse plastic jig purple, the end result will be anywhere from red to burgundy. Some of those colors are good.
I like to start with white, glow, clear sparkle or smoke sparkle and then dye them to get the combos I want. They are neutral enough to come out fairly close to the color of the dye.
The other way to change the color on plastic is to use a "worm paint".
As the label implies, this stuff goes on the top of the plastic and does not dye it. It is good for adding spots, dots, stripes, eyes, etc.
As has also been mentioned, you can use a good permenant marker pen to do the same thing. I use red, blue, black and purple to create contrasting stripes, dots and accents.
By the way, you can get either the plastic dye or paint at Barlows.
I am attaching some pics of my setup and the results.
