I just read ops_was_a_truck's kitbashing guide, and had a question about the dyeing process. I'm making a new thread since I figured I wouldn't get much of a reply in a stickied thread. anyway, I bought some black rit dye at walmart to dye alt. meister black. it said in the thread that you heat the water to 170 degrees, and add the dye and acetone. my questions are, what is the dye/water ratio, and what does acetone have to do with anything? all I know is that acetone usually melts plastic, so I'm wondering again how much to use and why. thanks, as this is going to be my first dye job, although I'm definitely going to dye something as a test first.
