How can I dye plastics parts? Please tell me where I could get the dye also. Thanks
You can paint or otherwise finish the surface, but dyes to color plastic are put in the plastic BEFORE it is molded.
Krylon makes spraypaint for plastic now and there are plenty of colors to choose from. This is sold in Wal-Mart or any home improvement center or paint store.
You can do a few things. Either way, it comes down to 'staining' as plastic parts don't have as many fibers as cloth materials do to hold onto color. First, you could get acrylic paint (at any art supply store) and paint the plastic part with a few coats (until thick so you can peel it off when it dries, wait for it to dry hard, not soft) In some circumstances you may be able to 'bake' or iron on color crystals or low melting point plastic beads to your item (though I wouldn't reccomend because your original item is plastic and though it may have a higher heat tolerance, I wouldn't want to risk ruining it (especially if it's part of a larger project) or there are rub on transfers usually intended for dressers, walls, etc, they will easily rub onto plastics as well (also in craft stores near the stencils for borders) they usually come with 1-2 sheets per package in a ton of different designs and a small wooden stick (looks like a cuticle pusher) to rub them on with. or you could always soak it in grape juice or wine or Rit (tie)dye.
