The system is ingenious and I am pretty sure it would work well for tops and backs. However, I found it very difficult to push the cleat off the device when reaching in to fix a crack in the side. I just couldn’t contort my arm and hand enough to have a finger able to push the cleat off while holding it in the correct spot. I could clearly see the position of the cleat holder on the viewing material, so that worked fine, and the actual wooden cleats were excellent and worth the money themselves. It was a tough challenge, and there is no easy way to fix some spots, no matter what tools or methods are used.
