I'm having some difficulties with painting Platsil Gel 10, I was recommended as a cheap solution to buy regular oil colors mixed with silicone. To thin it out I used a small bottle of chemical clean heptane/gasoline. But I'm not satisfied with the look,the substance is to sticky (see the picture)
Any other ideas or ways to get a persistent paintjob done over platsil gel 10 silicone? would be greatly appreciated
Doug, just to say I am really liking the d-limonene. Seems to work very well, and now my workroom smells pleasantly of oranges! Thanks.
Smooth-On sells a solvent called 'Novocs' for thining silicone for painting. It comes in two finishes, glossy and matte. The matte is what I use and I've never found a better way to kill the shine on a puppet! You can use it for all your painting or just use it as a clear topcoat.
It's possible to even use airbrush acrylic paint in your silicone but be warned, I've discovered that mixing acrylic paint in with your casting causes the rubber to form tiny air bubbles inside the rubber. So don't use it for a puppet you're casting that has to be super smooth because those tiny air bubbles cause tiny dimples to appear when the rubber is bent... but it's just fine for something like casting a realistic cyclops or dragon or something like that, in which case you won't even notice the tiny dimples.
