When you pay $1200 for an AAR hood, you expect more from Stinger Fiberglass
I'm no body guy, but if the fiberglass couldn't hold together on those corners, isn't some putty just going to blast outta those corners about the time you think you got it all figured out, right after paint and install?
That's not the kind repair I'd want to make on a 1200 dollar air-scooper-inner.
