Looks like the natural patina is a little overdone on this one. To far gone for duct tape or a wrap. Would make a nice Derelict build. Still trying to think what weird thing happened. Maybe the owner lived on the coast and parked way too close to the ocean. It could have been a Mob clean up crew's car and they spilled their jug of lye on the hood. No teeth marks so I guess strange monsters or aliens can be ruled out.
Thomas Dolby once had an album out called "Aliens ate my Buick".... Looks like they didn,t finish this one.
