Thanks for the advice. I have tried to tighten up the Monokote on a number of occassions. I 've used a heat gun and/or the iron with a protective sock on high heat concentrating on the two bay repair area. The Monokote certainly expands but does not shrink back tightly. I have venting for the heated air. I still have ripples over the open structure mainly near the corners of the repairs. I am concerned at this point that anymore attempts with high heat may shrink the plastic around the seams and melt the MK. I have an example of this on another area when I applied MK to an open bay without spanning the covering to the ribs. I've never taken the iron past 250 degrees on my repairs and I have blown the area with the gun repeatedly with high heat. Does Monokote shrink to a maximum limit after repeated attempts? I don't mind replacing the covering. It's the basic white under my Avistar wing. I am more interested in learning about the the handling of the plastics and the different results I can achieve.

Now while you are kind enough to respond, I have one other question(s). I have a new Sig 4* wing covered in AeroKote. After absolutely making sure the wing was properly prepared. I applied the supplied mylar decals to the wing running them along the spar. As I feared after a number of months, the only place on the wing that began to develope wrinkles is right under a portion of the decal. The decal is applied correctly to the covering. It is the cover that came loose from the spar. Can I SAFELY use my iron on the decal at a low temp to shrink the Aerokote without distorting the decal? Recomended tacking temp is around 200 degrees. What is a safe temp range? If I want to remove this decal will low heat and a careful "peel back" be the correct way of removing it?
