Ironing Wrinkles out problem GP Lili Tony
Hi All, I have been building and covering models for many years. Also have
assembled many ARF,s and have never came across this. I am building a GP
Lili Tony and the wings and feathers are covered in something that will not shrink.
I first sealed all the seams and edges then started on the wrinkles. They will not tighten
up with any amount of heat from my iron or the heat gun. The heat gun on high actually
made them worse. They did not respond to normal heat and when I get way to close it just
bubbles up and then leaves it worse. I will say that this stuff can take some major heat with
out burning through. I've got no clue. I just finished an aero works 75cc 260 and its ultra coat
is just perfect after sealing and tightening. What the heck! help please. Tim

If it's a GP model, it's MonoKote.
Two things you can try are:
First, poke a few pinholes in the area before you heat it. Now when you heat it, as the air underneath expands, it can seep out instead of creating a bubble under the covering.
If that doesn't work, try heating not only the wrinkle, but also the surrounding area. As the area around the wrinkle shrinks, it might pull the wrinkle out.

Follow MinnFlyer's advice. I have also had some Monokote-covered ARF's recently (TF AT-6 to name one) and I experienced the same issue. I actually had to recover the ailerons on my AT-6. The Monokote that came from my roll was different than the Monokote that was on the ARF. My stuff was slightly more transparent and more responsive to lower heat. I do not intend to start a debate about this stuff but there is definately something different. One possible cause could be that the ARF covering was heat shrinked eccesively at the factory due to a loose covering job and it is already near it's limits as far as shrinking is concerned. I also did notice that the ARF covering material seems "tougher" and does take/require alot more heat.

Thanks Guys! I combined all the tricks in the book and got the plane looking
pretty good. All that is left are tiny wrinkles that almost look like wood grain.
I will have to live with them, I guess. This monokote has alot of glue on it
which is good as it will not come loose.
Thanks Again

Minn,
Just 'cause its a GP don't mean its Monokote.
I had their Dazzler and it was some sort of vinyl.
Used acetone to take off an epoxy spill and took off the coloring.
That Dazzler was the worst designed plane I have owned.
I'm pretty glad it doesn't exist anymore.
I'm going to stick to World Models planes.
Good Luck,

I know, the rest of the plane was Monokote but the checker pattern on the bottom was something weird. When I got mine, the clear was separating from the color. GP sent me new wings and a new tail and that seemed to be in better shape.

Yeah, I figured it out the hard way while taking care of some wrinkles. I had the iron hot enough to work with the Monokote, which turned out to be too hot for the cheap stuff they put on the bottom. I'd have preferred that they mentioned the two different types of covering, rather than allowing me to discover it in an unpleasant moment.
