I am for the first time attempting to paint platinum silicone. I don't acctually know how so I looked it up and it says mix silicone chaulking with solvent and oil paint. So what does that mean? I can use the oil paints I already have for painting pictures mixed with what kind of solvents are acceptable? And the hardest part silicone chaulking? What's that? I looked it up and another website said you have to mix paints with only contractors silicone sold i. Huge $100 tubes i only need a little to paint a face? What is the cheapest silicone chaulking I can use? Links? Can I not just mix up some of the platinum silicone I already have ? Thanks!
