Has anyone tried dying white Traxxas parts such as 3655A with satisfactory results?
Who needs nitro, when you got LiPo?
There is a youtube video on it.
Long video short: Get "Rit" brand dye, boil water in a stainless steel pot. Add the dye. Submerge the car for 10 minutes. Rinse the parts. Repeat if coloring is not as desired (too light).
Note: The plastic needs to be porous, not sheen. Your use case is fine.
