In addition to the weathertech flaps, I placed this clear paint protection film at the bottom of the doors and rear panels. The roll is 6 inches wide x 84 inches long, so you only have to size/cut the length. The upper line is barely visible even though my RL is black. They have held up nicely for about 2 months. 3m is another brand that makes a similar product. The roll is about $23 US on Amazon. I believe I ordered 2 rolls as the first door application was a practice run!
