OK, I decided that I want to dye my Revo's wheels. I know the basic procedure:

Boil water
Add RIT Dye
Add parts
Take parts out once in a while

What I don't know is how much RIT Dye to use? I will be using black if that means anything.
Also what is something good to put the wheels in to let them soak? I don't know if I have something big enough to fit all 4. The reason I want to dye all 4 at once is so none of them end up with a different shade. Thanks for any help in advance.
