What type of insurance would pay for that type of Damage?
It is vandalism. Some of the Home owner policys will cover it, if was at home when the vandalism occurred. It would be worth your time to find out even if it occurred on the road.
The only thing that made an engine seize up completely was bleach.
To remove a locking gas cap all you have to do is pinch it while turning,it will come off in seconds and leaves no witness marks.
Pinch where? Around the large diameter, or at the little raised "handle"?
