Is the proper way when replacing wood in cushion bottoms, backs, etc to resin coat the wood? All the stuff I'm pulling out obviously wasn't, but I have my doubts that most was original. I only want to do this once, but wondering if it was a waste since the resin's integrity would be violated by the staples when re-upholserting, and resin isn't the most waterproof anyway. Just wondering the "right" way. Thanks!
