Chrome Painted Fiberglass Bumpers!!

What were the bumpers cleaned with before the first coat of chrome paint? The glass bumper on my Dart is black, I can't seem to find a color that would look with green.
I had to spread some evercoat to smooth the glass bumpers first to make them as smooth as possible. Then I primed and sanded with 800grit wet-dry, shot 2 overreduced coats of ppg sealer. After the sealer flashed i shot 2 heavy coats of ppg dbc black basecoat, let that flash then clearcoat. Let dry overnight!! Wet sand with 1000-1200 grit wet-dry then buff to high gloss. Then mist several coats of the chrome till desired finish!! LIGHT MIST COATS!! Let this dry(I let it dry overnight) and reclearcoat. Done!
