Interestingly enough, I have seen Tecmoto do a swingarm in gold paint, similar to the gold marchesini wheels. Smooth out all the casting marks and dimples and then paint. This looks good - it was on a 916 that was crashed and then done up as a red bull rep.
Probably tecmoto would steer you down this route. But like you L3oony, I'm a bling merchant

and can't resist a bit of polishing and autosol.
