I used a heat gun ( it looks like a hair dryer, but is sold to heat shrink things ... ).

This worked perfectly at the higher settings.

The key is to start on a small area, and once you notice it starting to initially loosen, start making small 2-3" circles.

You MUST get the surrounding regions to shrink evenly as well, so it is a mistake to concentrate only on one small area.

Enlarge the circles as you go working your way accross the component.

Initially the covering will seem to bloom out a bit as it gets warm, this is followed quickly by shrinking... which if you persist too long, is followed by tearing plastic or burning!

Keep the gun constantly moving to prevent damaging any area and to help regulate the temperature of the material.

Once you get the hang of this you can do a plane in just a few minutes.
