|A Sefer Torah that is Mashuach on the Back and Peeling.|

It would seem to make sense to remove the substance, if possible. I was thinking along the lines of perhaps (carefully) using an electric sander combined with an air compressor to blow everything away, starting first with a medium grade sand-paper, and then finishing it with an ultra-fine grade sand-paper to give it a nice, smooth texture.
Does anyone have any experience with removing the coating, or any suggestions about how it could be done, or why it shouldn't be done?
Would it perhaps make sense to instead clear-coat the coating with various clear-coats artists use to protect their paintings, so that the coating stops peeling?
