These things are not flexible polyurethane, they're "solid" fiberglass, I see no reinforcement. I rammed a parking block and it took a small piece out but nothing major, most of the damage was shown because it took the paint off and showed the white fiberglass. I did mention the 3M clear bra stuff, and also listed why I would not go that route. My friend's WRX's front is completely covered in this stuff and to me, it's just not worth it. The stuff is quite expensive to boot. It's for people who are worried about the resale, not the now. Until they start making the stuff cheaper and more transparent, count me out.
