Au contraire. I dropped a monster log on my (metal) BX hood at 10 hours. I was lifting it into a dumpster and didn't roll the bucket forward. For a moment, I was the little guy on the left FEL warning label. Anyway, BIG crease all the way across, pretty much even with the side rails. It's a guess, but I doubt the plastic hood would survive that. Maybe if it was ABS, but it can't be - too much heat.
30 minutes with an assortment of hammers, mallets and round objects I had the metal hood back to almost new. It's hard to spot.
Not to mention what I have done to my rear fenders. I wish the blinker housings were metal too.
