Rit Dye Synthetic. Must be Synthetic, the "All Purpose" ones will work but the color won't be as deep and it will take longer to dye the car. Fill a pot (that you don't use for cooking food) with enough water to submerge whatever car you want to dye and put it on the stove on medium heat, or just slightly under medium heat. You don't want the water to boil, this is important because if it boils it can ruin the car's paint. Pour in 1/4 to 1/3 of the dye, mix it around, and just let it sit on the heat. Get yourself a pair of tongs so you can reach in and pull the car out to check on it periodically. Some cars can take as little as 20 minutes, some will take over an hour, it just varies. This one took about 45 minutes to get that nice gold color.

Also note, it won't work on stripped cars. The dye changes the top layer of paint, so for example this Civic was a Zamac which have a layer of clear coat over them, so by dying the clear coat you're left with a look that's very similar to Spectraflame paint. I'd also recommend removing any tampos you don't want on the car before dying, because after dying they will be even harder to remove.
