When exposed to drier air, the wood loses the excess moisture,
dimensionally shrinking microscopically in the process. That's all
it takes to cause some slight relaxing of the covering, causing
wrinkles to appear.

Any wrinkles that appear in the covering are easy to remove by
applying a little heat from a small modeler's heat iron.  Because
of this model's small size, we do not recommend using a heat gun
to tighten up loose covering.  A typical hobby type covering iron
will work just fine.  Even better is a small modeler's "trim seal" iron,
which is perfect for controlling the heat applied to a specific area.  

First, use the tip of the hot iron to go over all the seams and color
joints in the covering, making sure they are all sealed down and
well adhered.  Then, hold the hot iron over the wrinkle to lightly
shrink the material.  Be very careful whenever working around
seams.  Re-heating seams can cause them to "creep", making
them unsightly.  A very easy way to avoid damaging seams and
joints when re-shrinking the covering is to protect the seams with
wet paper towels rolled into strips.  These are placed directly onto
the seams and their coolness protects the seam from shifting or
"crawling" under heat.  You must also be careful when using a heat
iron or heat gun when working around the window and windshield
areas - heat will distort these plastic pieces.
