Thanks for the input. Years ago, I searched for a long time to find a nice original hood to replace the one I had that somebody installed hood pins into. I still have the hood pinned hood if I get desperate. I remember back then that everyone had a low opinion of the repro hoods. I had hoped that things had gotten better over the last ten years. Guess not.

I wouldn't repair BC/CC; I'd respray the whole panel.  Over time you'll have issues with where it was blended.  Honestly, since its a hood anyway I'd just respray the whole hood and be done. 

As for the insurance claim, how well do you know your agent?  Were I in such a situation I would simply call my agent and talk to him about my best course of action.  There's a lot that could come into play in something like this.  The damage resulted from a failure in a building, not another car, or even a stationary object on the road.  My gut says the car insurance would look to make the homeowner's insurance pay for it.  Its all in how the various policies are worded.  Then if its on the homeowner's policy, is it worth starting a claim history and losing the deductible?  My homeowner's deducible is so high it would never be worth it (I use insurance as catastrophic loss coverage because I'm a contractor and would fix it myself anyway, so its not worth paying higher rates for a low deductible).  If your deductible is really low it might be worth it, but on average homeowner's deductibles are $500-$1,000, so probably not.  I think my first step might actually be to get a price on doing the repair.  Then you know how much you are talking about to help inform your decision. 

I'd definitely use an original hood if it needs to be replaced.  The old hood with the pins could be repaired I'm sure.  That would be a better course of action than a repro IMO.

Report it to them immediately.  They will cover everything, except maybe your underdesigned shelving.

I doubt they will cancel you unless you have repeated claim history

Your homeowners insurance should cover the shelving, but they will put a red flag in your file for “next time” and the deductible probably makes it not worth messing with.

But definitely get Hagerty involved with the car damage.

And, be advised, Dynacorn hoods do not fit worth crap.

I agree with this.

Your damage was caused by falling objects, which is a Comprehensive claim under your policy. Neither insurance carrier for which I worked, State Farm and Farmers, increased your rates for Comp claims.
