this is what i found on weathertech!!!!
I installed this on my 2007 Toyota 4runner back in 2007. Installation was easy enough--no drilling required. Only thing that needed to be done was to loosen the front grill plate to slide the edge of the deflector in, and then 2 screws to existing holes on the underside of the hood and it was secured...
The deflector seemed to work well enough--I'll never know. I still got innumerable bugs etc... as well as 2 rock chips that eventually cracked the windshield requiring replacement.
HOWEVER, I decided to take the deflector off yesterday, and when removing it, noticed that where the deflector sat flush against the front of the car hood (where it tucked into the grill edge) there were numerous (over 1 dozen) paint pit marks--undoubtedly from where the plastic rubbed directly against the paint. Even worse, the pits were all showing rust!
I just sent an email to Weathertech yesterday, and am still waiting for a response--I wouldn't hold my breath however, waiting for a resolution.
This deflector WILL rub your paint and eventually cause rust. The only way it can avoid this would be to re-design a full-floating deflector, a relatively easy fix.
I would AVOID this bug deflector (and probably all other ones)!!
Here's the photographic proof of the damage caused to my hood:
