4004 Transparent Base.
4004 Transparent Base is the colorless resin base to Wicked Colors and Auto Air Colors. 4004 appears milky in solution yet dries clear. 4004 works as a low-build inter-coat, transparent extender for colors and as a non-reactive barrier to prevent bleeding when using Candy 2o. T-shirt painter may also wish to apply a light coat or two of 4004 onto the fabric prior to painting to lock down any fabric knap.
