I like the looks of it. I think it matches the moonroof deflector very well. The screws through the plastic are painted/coated. Mine in two years looked new. The issue is the foam strip underneath harming the paint. I put a narrow strip of 3M Clearbra under it and had no issues on my '11. On my new '13 I went with the "bikini cut" bra(about 1/3 of hood) so I didn't have to deal with the small clip protectors.

I've had the hood protector on my car for 3 years. I would say don't even install the foam backing strip. Too much debris gets caught it in and it will loose it's adhesive anyway. I haven't had an issue without it, my rubber stoppers on there hit the hood long before the plastic would. I did install those rubber stoppers in slightly different locations than the instructions suggest. I also have a clear bra under the hood protector though, so I haven't been too concerned.
