RE: Has MonoKote formulation been changed?
Ok, Here are my results from frets 24 samples of monokote he sent to me and Deadeye. I was waiting till I had a wing or something ready to cover but it will be a while before I build another wing for covering so I made a make shift "horizontal stabilizer" if you will. It is a piece of 3/8" balsa that I cut to shape and sanded the corners round. This is a test to see if the monokote can conform around tight rounded corners like this one. Frets 24 sent me the yellow covering only so that is the only covering in question. But to start out, I warmed up by covering with my own roll of white monokote. I cut a piece of monokote to cover the bottom side so I could get a feel for how the monokote I am use to would conform to the curves. So, the results of my white monokote are of course, went on very easy, great adhesion, nice stretch ability. When it came to stretching it around the curves it did very well, just as I suspected. I just kept tugging and ironing around the curve. Little by little, it stretched and ironed smoothly down around the curve. I then trimmed it with an x-acto blade and sealed the edge off completely.
Now, I flipped over the board to try out this "new" monokote in question. I cut the sample in half to save for another test. I already mentioned that the yellow monokote had all the same tendencies and characteristics of the monokote I use. It feels, looks, and smells the same and has the same shiny finish. I started by ironing it down smooth on the flat surface first. One thing I noted was that I had to turn up my iron ever so slightly from 1 3/4 to about 1 7/8 (on the topflight iron). To me, there was a sufficient amount of adhesive to stick the covering to the flat area of the balsa wood. I then began stretching it little by little all around the rounded curve. Again I noted to myself that this yellow covering tended to stretch just a bit more and easier than my white covering. I got the yellow covering to conform pretty much all the way around the curve to reach the other side. I had no notable “bad” tendencies (I know hard to believe by many but its true). Once the yellow covering was stretched over the curve, I trimmed the excess with an x-acto and sealed it down the seam. All in all, I still cannot figure out why anyone is having trouble with Monokote. Again, I know by now all I am doing is just blowing hot air at all of you because it’s not like this test will change any one of your minds.
