What type of ATV do you ride, and what area of your ATV's plastic has the most scratches.

I ride a Raptor and the tops of both the front and rear fenders receive the most scratches.

 

I have a Y2K Mojave. It's scratched in the same places as your Raptor, mainly from branches on the trails. The area behind my legs have a "sanded" look from my boots rubbing dirt against it. There is not much you can do, if you ride in the woods, it's going to get scratched.

I'll bet duners have better luck avoiding scratches...
