I was de-wrinkling a new ARF today and I thought of your first post.

Your heat gun setting is TOO LOW.

That's right too low.

It's almost there but not quite high enough.

As a result you are getting partial de-adhesion, but you are not getting the shrinkage that accompanies a slighter increase in heat.

This just makes things worst when the covering cools.



Use an adjustable gun and set it a bit higher.

Then make small 2" "circles" over a small area on the covering.

The existing wrinkles should start to join up into larger bubbles that should start smoothing out.

As the heat is increased you may see a SLIGHT discoloration of the covering ( It will return to normal once it cools off ). At this point the covering will begin to shrink and the bubbles will smooth out even more.

When this happens widen the area a bit. You want the surrounding covering also to shrink and pull at the material you are working on. Keep moving the gun constantly and move onto the surrounding areas.

If you find that you get a large bubble which you simply cannot get rid of, poke a pin hole or six in it. These will disappear later.


My covering initially started to look just like yours ( hence I recalled your post ) but since I've done this so many times I just turned up the heat a bit and 15 minutes later I had finished the entire plane.


You do need to be careful as different covering has different heat tolerance.

China-Cote seems to need slightly more heat than Monokote or Ultrakote, but be careful. If you go a bit too far it will start pulling away again.
