I was using Oracover lite to cover my Butterfly (Diversity model
aircraft). The covering material has a layer of glue attached to it.
The instruction of Oracover states that at low to medium temperature,
the covering material will bond, and it will only shrink at high
temperature.

I finally found a temperature at which the glue melts and bonding
happens, but at that temperature the covering wrinkles severelyas
well. I was covering balsa sheets and wasn't able to get a flat layer
of cover. The covered surface looked like it was covered by those
thin plastic transparent covering sheets we use to keep food fresh in
refrigerator (what are they called?).

To add to my problem, I think the sealing iron's temperature was not
stable (I got the cheapest sealing iron with a Hanger 9
label). Without changing the temperature setting, sometimes the glue
won't melt (only the covering wrinkled), and sometimes the covering
melts. Most of the time I get wrinkled finish.

Help and thanks.
