I have been trying to dye a classics Prime to black... I have tried everything listed! 1. boil in black dye for 5-10 mins 2. boil in acetone & black dye for 5-10 mins 3. heat dye to a boil and then let it cool for a bit then place piece in black dye for 30 mins. 4. leave for 3 days in room temp black dye It doesnt even take on ANY black color at all! I have even scuffed up the plastic with steel wool, sandedit and soaked in in 90% alcohol over night then trying to dye it.... with NO luck! Help please! What am I doing wrong?!
