Hopefully someone that has actually done this will post, but in the meantime, here are my thoughts.
I don't think its going to stick to the plastic very well, at least not for any long period of time, and especially if you run through brush etc. I have a Sahara, when my painted flares started getting scratched I sold them and bought the black flares (Craigslist) that come on Rubicons and X's/Sports, the color contrast looks much better and the textured plastic doesn't show scratches. I actually made a small profit doing the switch, the right person will pay good money for your painted flares if you haven't sratched them too bad yet.
Also, if you ever damage a flare, it wouldn't be nearly as hard to find a single black flare as it would be to find a single painted flare to re-bedline.
If you do bedline them, post pics. I personally haven't seen this done yet.
