An idea for all your feedback

What about adding the diamond plate to the bottom of the doors, like an 8-10 inch strip ? That would look tough and prevent rocks from scratching the doors.

The only thing I have seen that would really help are the door magnets, and the cables run from the top rack to the brush guard. It "lifts" the big branches and prevents the deep scratches.

However:
The Line-X is so practical, cheap durable and easy to apply.
