I had a GTS Bug (GT Styling) deflector on my last vehicle-- a Honda CRV. It matched the hood contour and fit under the hood and then attached with 6 or 8 3m (velcro-like) dots. It stayed on well and I think prevented some amount of rock nicks to the hood. I liked the way it looked. Here are a couple of things I learned from that particlular bug deflector:
- It didn't touch the hood (was raised up by the velcro), but it did catch "junk" under it (leaves, pine needles, etc). You need to clean that periodlically and make sure nothing is scratching the finish.
- The 3m fasteners-- they were that clear really strong stuff-- over time and use got brittle and lost its grip. The adhesive on the back of it was pretty tough to remove when I needed to replace the dot. The finish seemed to survive, but I hated the effort.
The net is, the product was good, I liked the look, it may have saved some chips on the hood, but it was kind of a pain to deal with.
