After the second application of primer, wait at least 1 more hour before using the oil-based paint on the silicone.
How do you make paint stay on silicone?
A good method of creating a flexible paint is to use an oil-based paint (your chosen colour) alongside silicone caulking. To thin it down, use orange solvent or white spirit. You can then paint the silicone, and the solvent in the mix will evaporate (leaving the coloured silicone before curing).
How can I change the color of my silicone?
Mix the silicone and pigment together with your stirring stick. Combine the two materials until the silicone has the consistent color you’re looking for. Add more pigment if you’d like a deeper color, but do this gradually; remember that you can’t remove the dye once you’ve added it.
How do you make a mold out of household items?

Is bismuth good for casting?
Some bismuth-based low melting alloys from Belmont Metals that may be used in casting include: Bi-Pb-In-Sn-Cd Eutectic Alloys: This low melting alloy is a very good castable material as it has a low melting point of 117°F. So it can be used with other materials such as plastic or silicone without distorting it.
