Thanks for the help. Below is what I ended up doing.

1. scuffed the duplicolor paint that I applied weeks ago with a scotchbrite pad to help promote better adhesion
2. two med-heavy coats plastikote Chrysler orange engine enamel
3. two med-heavy coats plastikote clear engine enamel

Results are absolutey WOW! The shine is amazing and exactly what I was looking for. On a scale from 1-10 the I would rate the Duplicolor a 3, and the Plastikote color followed by clear a 10.

Thanks everyone for your input, Rob
