So I have an abundance of cheap acrylic paints from wallmart and they have done the job pretty well, but I think I have heard from punished props or someone in one of their videos that you can water down acrylics and use it as spray paint. Anyone have any clarification or tips? And also I want to use some masking tape. I'm used to free handing but I want to make a good design. I'm working on the recruit charred helmet and want to paint the skull and flames. Any suggestions on how to get it to that shape? I'm afraid of using an exactoblade on the helmet. I dont want it to cut through the tape and go into the helmet. Thank you!
