What can I coat this acrylic panel with in order to sublimate on it?
I have always really loved to apply weird organic textures to digital drawings I make (example of inkjet transfer with textured panel in second image). I want to try sublimation on this gessoed panel but I'm not sure exactly what coating I would need to put on to do it in the safest most effective way. I thought maybe heat resistant Rust-Oleum clear coat and just go outside and wear a mask to sublimate but I'm not sure. Any ideas?
