Last one,
In the car.
All told I have maybe 2 maybe 3 hours worth of time and maybe $30 total in paints. Both myself AND especially the cars owner. We were pleased with the outcome.

I'll admit, if I had it do over. I might get costs estimates to have them dipped and plated correctly and then weight the options.

But for the hobbiest doing there own car, this might be an option - as to them it's just materials costs.
