Thanks for posting the picture which shows color bleed and which will get worse within a week. Spike-It sells a paint that is applied to the plastic's surface in a thin surface layer and can not bleed. It dries fast and can't come off.
Spike-It dye on the other hand does bleed as well as fade and a bright chartreuse lure after dipping will dull if black or other dark color is applied to one side for example. I apply dark colors to the tips of highly textured lures and don't have to worry about bleed. Note the bottom swimbait:
Still the same after 1 month. Now I wish it could only catch a fish....
