I know this is an old thread but I realized something today and felt compelled to share it. I have been using Monokote for many many years and have never had one issue. I've covered quite a few planes and used a lot of different colors. Over the years I've amassed a decent collection of the stuff. Some colors I consider base colors I've bought 25 foot rolls, so I have plenty to compare.

Over the last few weeks I have been covering a recent project. It's about 50/50 red and white and I also covered the bottom of the wing and stab with a large black and white checkerboard pattern. I realized early on I wouldn't have enough whit and red to finish so I made a trip the hobby shop and bought a couple of more rolls. Not really giving it any thought I grabbed the new rolls and opened them, cut my peices and ironed my 2 colors at the overlap. This is where the fight began. The adhesive doesn't really grab without very high heat. When I applied it to my fuse I tacked all the way around the edges. I pulled on that stuff like a gorilla to get the wrinles out. Once I applied the heat from a heat gun the stuff relaxed and made some nice big wrinkle that I worked for hours to get out. I finally got the bottom and sides done and when it came time to cover the top of the fuse I went digging in my scrap box for a small piece of red. I found a piece about 8" wide and a foot long. Boom Boom the stuff went on great and shrunk beautifully. It was then that I realized the stuff felt different. Aside from the adhesive being different the film is different also. The old Monokote was from a roll I bought about 6 or 7 years ago. The film feels kind of like a candy wrapper from a peice of hard candy. When I crumbled it you can hear a definate crunch. On the new roll however the film has a softer feel even when I crumple it. I hope my description makes sense. On a whim I pulled out a micrometer and the new Monokote was thicker than the old. I also verified this with some other colors both new and old.

A couple of months I covered a foam wing with Econokote and it went on like a dream. There is definatley something different with SuperMonokote both in the adhesive and the film. I can't buy the epa regulation story because Econokote doesn't seem to be suffering the same fate, at least the stuff I bought recently.

It's a shame really because I really liked Monokote in the past and always felt it matched my covering technique better than UltraCote. I guess I'll have to work with UltraCote more because the frustration just isn't worth it.
