We just had new tile installed on our bathroom walls. While tearing out the old vanity I unknowingly stuck an oscillating tool blade through the vanity drain stub out. The cut is the white line at about 5 o'clock in the picture. Opening up the wall isn't an option. Can I just epoxy the cut? The cut is about 2 inches in measured from the front of the adapter and maybe 1 inch from where the drain curves down.
