Hey bdorman,
Enamel paint will bleed very bad if it comes in contact with todays plastic jigs and some skirt material. I have ruined many jigs just using enamel for the eyes. I use powder now and use to use vinyl for the eyes but have switched to Createx Wicked paints after many tests. The Createx is water based acrylic and easy on everthing. I left jigs I painted with Createx Wicked in water for 3 weeks and no fading. If the Krylon is acrylic I would give it a test! Be sure to put some in a small bag with some plastic you use and see what happens.
Life is Good !
