Driving down the freeway I have noticed my bug guard vibrating excessively. Thinking about removing it (decreasing drag)and replacing it with Rhino lining. If done correctly, I think it would be a great way to combat rock chips.
My previous AVS buguard took a big shot form a rock that was about to hit my windshield and busted into and kept me from getting a pretty good dink in my hood so I didn't hesitate to replace it with another and both have never had rattling issues. I don't think bedliner would've done the same.
