My fiance (after she read my posts) says I must clarify something to you- there are two different colourants they use to dye paints- one is a hybrid colourant they use for both oil and latex (usually used for commercial paints) and another colourant they use for industrial products (High end epoxy or industrial machine coatings). You want to use the industrial one. At Glidden Paints or Colour Your World (paint store chains here in Canada) use the industrial colourant to dye a product called DEVOE, high performance coatings:

If you ask for that colourant the sales people should know what you are talking about- if they don't then they are new, and should be shunned LOL
PS- If you get this stuff on your skin it will stay there for about a week- no kidding. If you get it on a rug, or clothes, or your puppets it is there to stay. So make certain you are wearing your Sunday best when dealing with this stuff...kidding...if you are using it for a nose make certain it is totally dry before attaching it.
