Honestly, I have yet to find a paint that provides a true metallic sheen like chrome or gold/silver foil. None of them end up looking like what you see on the cap. The caps are actually plated by a plater, not painted with the paint inside the can, so they cannot be trusted as true representations of the paint. I tried a Krylon Original Chrome paint in a computer case I modded years ago, and it came out relatively shiny, but nothing like the cap. I'd suggest it would never hold up to actual running conditions, only good for a shelf-queen.
I painted the drive bay doors, horns, teeth & fan with Original Chrome. It has a satiny shine to it, but nothing like the chrome-plated cap.
EDIT: Acetone works to remove most kinds of paint from nylon. I've found Easy-Off works even better. Both of those will attack plastic, though...that's why the acetone ate up your Tamiya parts.

But it's safe on nylon.
Why not dye the wheels with RIT dye or something? It won't be as "bling" but it'll be a lot more durable of a finish.
