if you were off duty, would you tell off someone for parking in a handicap spot, fire lane, or fire hydrant?
I don't think you can once the resin has cured. I assume the board is multi layer and you want to look inside. You will have rely on purely electrical testing methods to determine the position and type of fault.
If you went over these speed bumps slowly I wouldn't put the blame on the owner of the lot but the repair shop probably gave you a warranty and they need to get a blow torch and put those flex pipes on right.
