Paying top dollar to re-chrome parts the real way is not a realistic option for most of us. I heard about this idea years ago. This is not ideal but it's something I've been meaning to try. I had a badly pitted license plate holder so I decided to experiment with the Poor-Boy's way to revitalize pitted Chrome.
You be the judge...
After cleaning and lightly sanding the roughness off the pitted areas I tried multiple coat of primer in hopes of building up the pitted marks enough to sand the surface level. This proved impossible because the pitted areas were just too deep.
So I took Bondo and spread it over the entire piece. Sloppy but easy.
Then I sanded it leaving just the Bondo in the pitted marks.
Then I primed it again with three thin coats.
Then I applied 3 coats of basic Rustoleum Chrome paint.
Good enough? For $10, I'm happy. But if I were rich, I'd pay for pieces to be re-chromes by an expert.
