I always thought it looked pretty sweet depending on how it's applied. Sometimes it just doesn't look right. Looks good on some paint jobs, when they swirl the gold to give a turned look, not good on rearsets and other cycle bits.
There's that post for the diy egli where the guy literally built the whole frame himself. He seems to be a machinist. He made several bits himself like the rearsets and such, turning them afterward. Just didn't look right. I guess it's because of the nonsymmetrical shape of them clashing with the circles. But put them on or framed in a rectangular shape, a la a painted section on a tank, and it looks great. Oh yeah on Trans Am dashboards too.
