The problem with tye dye is that the colors radiate out from a central point. I have to dunk the entire part into the color and it would fade the direction I dunk it and since I cant dunk the center of the part first, it's pretty much impossible. I can get pretty creative by painting the colors on if the parts aren't round. I could also start in the center with a color, mask it, bleach, dye, mask, bleach etc to get a pattern close to tie dye. Would take a lot of work but I'm 100% sure I could do that. would cost a bit more in masking though.
