if realism is what you seek, take silver brush paint and paint entire exposed surface quickly. before dry take a cotton swab and start removing paint to give the desired finish you are looking for. use this on every chrome piece except front bumper and mirror faces. work quickly with swab until achieving desired appearance. for front bumper rub lightly with a clean dry tissue only with no paint. next, throw away all the gimmick paints on the market. this all works well on cars also. I have personally used this technique since the early 70's. if you are unhappy with the results clean part with thinner and try again.
