RE: Wheel Dyeing
I used black liquid rit dye on a new bumper, I followed the instruction first and it did not quite came out black, more like purpleish brown.
So I use full strength with out water and boiled that for about 3 minutes and let it sit for many hours. Still did not came out black, but close like very dark brown.
Other than black, I used orange on my rims and I followed the directions except I soaked it longer and it came out pretty good.
