Is this an acceptable insurance claim?

Well, your being a bit paranoid - but in this case - it will come back to bite you - if you'd called another insurance carrier or a different agent or never mentioned your policy number - to make an inquiry as to coverage for your projected loss - maybe nobody will get wiser - but in my experience no good deed goes unpunished. Your insurance company will allow your "hood to be painted" but not offer to renew your policy. Hopefully - you'll be able to get coverage. But honestly - if this only costs 210 to fix - why bother with the insurance? Save it for a really big accident so that you can get a whole new car.
