This is what I used
Cowles T3402C Black European Body Molding : Amazon.com : Automotive
It's nice polyurethane stuff. The color and texture are consistent right through so that when you cut it, the cut end looks the same as the rest. I cut it to length (front door 41.5 " starting 3/4" from front edge of door. Rear door 22.5" again starting 3/4" from leading edge of door. Once it was on very securely, using a new razor blade,I trimmed the front edge of both moldings on maybe a 20-30o angle towards the front and made sure the back ends were perfectly squared off. This stuff trims very nicely, almost self healing.
put some blue tape right up against the edge that you're trimming to protect the paint if you slip with the blade. Once it weathers in a little, you'll never know it was a cut edge.
I hung mine about 1/4" below the body line, so that the overall width from the body line to the bottom of the letters is about the width of the 2013 chrome molding.
