If you dry the covering off, the residual glue reactivates when reheated. The best way I found is to strip the old covering- any way you do it. Mine was so bad, I just ripped it off. Most of the clear polyester came off, colour remained on the wood. Then I ironed over some news paper and pulled it off while still hot. This got most of the color off but left the surface sticky so I did it one more with a fresh newspaper. Finally I ironed down over cloth and did the same as the newspaper. This gets most of the goop off. Then I recovered. I found best to use the same color as the original monokote so any residue did not show. Use sand paper where possible, I used it only where there were repairs
