first, i left my plastic molding on, i painted the endcaps and the side molding with gloss black krylon fusion (its made for plastics) its held up awsome for a year. im sure they sell it in a silver similar to your jeep.
use a hairdryer to heat up the glue under the molding then carfully pull it off with a PLASTIC putty knife. wd40 actually works well to take off the residue the glue leaves behind. heres some pics
