Thanks, dude. I actually gotta give props to Seaball/Chris Goetz. I got to check out his quasi-Schuie-car at Cleveland this year and it looked great in black.
I did however decide to keep the purple anodizing for a little contrast against the black.
I had no warping issues with the Schumacher plastic whatsoever and I used regular Rit black dye in the bottle and added a good amount to the water. I then put the parts in for about 20-30 mins at a simmering boil (if that makes any sense).
If the parts are still purple after 30 mins, just leave them in the solution longer. Once you're finished, just get them out with a stainless steel strainer and put them in the sink under cold water. It'll take a while to get all the excess dye out while rinsing so be patient.
