I had built a Dental clinic and it was in the finishing stages. The Dr asked if he could hang some paintings, I said sure!
Next day he sheepishly came to me and said I did something BAD. He drilled a nice clean 3/8" hole thru the drywall and also into the face of the Pocket door. I had some perfectly matched wood putty and filled the hole nice and smooth and then sprayed a few coats of Satin Lacquer over the area. Couldn't see it unless you were right on it. He was happy. The alternative was to RnR the door at at least $1,000.
