I used my Smart 451 keychain for inspiration. Its a toy i keep on the side so did not feel like dropping $ on proper wheels for 4 months a year (canada)
The result. Not sure if i like it but its growing on me, and others who have seen it.
Process: scuffed them up with some Scotch brite. Taped up the two silver signs on the center. Sprayed them gloss black at a bodyshop. Removed the tape and bought some Yellow Vinyl to stick on and left the silver as is.
Sorry for the crappy pics i took these REALLY fast.
Next Step:
Smoke the tail lights, tint the windows and MAY smoke the headlights. Not sure about the headlights though.
