If your worried about scratches. I tried something different. I purchased a roll of magnetic vinyl wrap. About 100 bucks for 2ft by 24ft. I cut it out to match the doors and rear fenders. I only put it on when it's time to hit the trails. It protects the paint from rocks and branches.
It Does not work for the front fenders but hey they're pretty far off the ground . It comes in many colors but I chose black. It's the same stuff they make magnetic signs out of.
Where do you buy something like that?
