The reason that I said that you couldn't dye DX plastic was because I tried it and the dye didn't take after about 20 hours of sitting in dye. When it did finally take after about 48 hours it looked faded. I think you are better off using colored sharpies on dx then wasting all that time with a disc in dye. Just my 2cents. Maybe different runs of dx and ProD takes dye differently but I didn't want to waste that many days trying to find one that did.
