You ever try to do something with the stuff that peels off of Monokote? I took a wing frame and painted on Balsarite full strength next day I tried to stick the plastic on it with an iron. It looked like it stuck until I shrank it and it popped off the frame. Why didn't it stick to the Balsarite?

Because it's polypropylene and nothing much sticks to it? That's why they use it as a backing, it can sit there for decades and not stick.

Are you saying that you tried using the M'kote backing material as a wing covering? If so, Brett's reply says it all.

It's not crazy, you have all this nice plastic lying around, and it seems natural to want to use it. It doesn't work, of course.

I have used it to protect my plans from glue before...

I use the backing for protecting plans. Also cut into small pieces to seal the canning jars I keep my SIG & Brodak dope in.

It's good for masking.

Try scuffing it to give the balsarite something to bite on to.

You can try, but its used as a backing precisely because nothing sticks to it. Don't count on it without extensive (to destruction) testing. Any of these waxy plastics are almost impossible to bond. If they need to be joined, they are typically welded.

Just one of those dumbbell things many years ago when monokote was a very new thing. In the days-of-old when USA companies ruled the Model Airplane products, TOP FLITE was an independent company, and they brought monokote to the USA modelers. One of their employees at the time was a young fellow from England named Dave Platt, one of the great minds in airplane design, production and new materials.
Top Flite had marketed a covering material, forget its name but it was garbage and called by those that tried it, "Instant Wrinkle" HA, HA!
Well, about 1970 +/-, here comes the new stuff called "Monokote". It certainly did not take long to become the RC modeler's favorite item for covering. Probably same for CL.
Here is a funny story: I owned a Hobby Shop in Mt. Prospect, IL at the time. I built a C/L profile model to test this monokote. Up flying and all of a sudden a great glob of RED departs the model, but it kept flying. I was just waiting for the big crash, but it did not come. When the engine quit I landed and ran over to find a plastic like stuff over the outboard wing. I hurried to call Top Flite and spoke to Dave Platt. He laughed and accused me of leaving the backing on the monokote. HECK, I would NOT do such. n1 It just had to be a separation of the coloring thing!! %^@ n1 y1 HB~>
Well good 'Ol Dave had it right. He never let me forget it either! ;D However to this day I never figured what held that backing onto that wing. It peeled right off, and it was on top of the bottom wing covering at the LE and TE. If I saw Dave today, he would probably ask if my monokote still sheds its coloring! :##

Don't feel bad. After covering I don't remember how many models with Monokote I was in the process of trying to cover an elevator. The covering would not stick to the previous Monokote. I even turned the iron up more and that I when I discovered I had forgotten to remove the backing. It would stick until I tried to shrink it. ~^

It is my glass layup peel layer of choice. Never sticks, will conform to reasonable curves, and is the right price. Typically use when bagging/pressing race plane wings, tails, and profile fuselages. I like it better than the mylar that you can buy for layups.
My only problem is that (a) I sometimes run out; (b) you need to handle it carefully when you are at Stage I, which is when you are peeling it off of the MonoKote for its "first" use, so that you do not cause puckers. These will show up in your glass job when used the "second" time as a peel layer.
I have also used it as a plan cover, but it doesn't seem to have overall advantages over Saran wrap or waxed paper--just different.

Some great suggestions here, all these years, I never thought of using it as a plan cover, heck, I'm still using waxed paper!!!!

Well here goes my secret use for backing material from Monocoat! I have been making Monocoat hinges for my film covered creations in as much as I no longer have a full basement to call my own! I have had to adjust to one large bedroom as my domain. By using film I don't irritate the love of my life for the past 51 years with " That horrible stuff that is stinking up my home"!
i USE THE BACKER TO PREPARE mONOCOAT HINGES BY using it to help me not stick the opposing pieces of color matched material to form the hinge. I protect the sticky sides with the film and also use paper towels to iron through. If the plane has one color up and another down I make my hinge halves out of the appropriate color to eventually mount them in the age old X fashion.
To prepare the surfaces to receive the hinges I put a piece of film around the edge to give the hinge something to stick to opther than wood. I hinge the entire surface which is to say the hinges go all the way across the wing or stab from root to tip.
Incidentally the hinge strips are prepared in about 6 to 8 inch strips and are then cut off to fashion the final hinge. These segments are about 3/4 to 1 inch lengths.
