Sorry for the slow response; I had to dig out the sealant from the bolts at the bottom of the slide out. I then resealed the holes with silicon. Couldn't get one bolt out because it wouldn't slip past the ledge so I cut it short and sealed it in place. Looks ok to me!
Good luck to you... the table pedestal came from camping World on line. It was a flush mount that the slide will pass over when retracted.
