Thanks MasterWK and machinanyc! I took the letters off, sanded till the chrome was hazy. Then I used Self Etching Primer followed by sandable primer. Sanded smooth then reprimed with sandable primer. Hit them with Black Acrylic Enamel and sanded them some more followed by more paint. Now I'll let them cure and clear coat them this weekend to give them the polished look. If anyone wants one, I'll put together a How To. I have some extra of everything and some other badges I pulled off.
