I found my roll of Econokote in the shop. Went on like a dream - no problems with the shrinking at all. Quite a bit more transparent then the Monokote though. Can't say I've ever had a problem with Monokote sliding around, adhesion of the Monokote I was having the shrinking problem with seemed to be great. When I pulled it up to replace it there was a very good track of surface wood on the piece. I tried some of the problem roll on a mock up frame I threw together quick and had the same issue. As best as I can describe it the Monokote would swell over the open span just as it does normally right before it begins to shrink tight except that in this case it never shrinks. It just maintains a rippled appearance. I kept adding heat with the gun to see just how much it would take which only resulted in a burn through without any further tightening.
