No, are you real sure you would want to do that?
Isn't the job of the flare to save the paint from rock and other carp thrown from the tire? How would paint hold up?
Would it not chip and crack?
The flare is the same color all the way through and won't show as bad. The bottom line, it's your truck and you can do whatever you want. Good luck on whatever you decide to do and please enjoy your Rebel. That's what it's for.
If you were going to paint them it would be best if they were done off the truck. They attach with push pin retainers and double sided tape. If you wanted to paint them I would buy and paint replacements and then install them after. They are a little over $100 each from Chrysler.
