GENERAL. Any irregularities in the wood surface will
show on the covering, so a good covering job should
be preceded by careful sanding, filling of nicks and
dents [we recommend CGM Model Mate™ balsa filler),
and then more sanding. For this final sanding, use fine
sandpaper (240-320 grade) and a sanding block.

The easiest way to finish your model is to cover it in
one color of UltraCote and then apply trim in a second
color, using either UltraCote or sticky-back UltraCote
plus. Both UltraCote and UltraCote plus can be applied
on top of each other without forming gas bubbles. (If
you use another brand of covering, follow manufactur-
er's instructions.)

You may also paint over polyester plastic films, as well
as the plastic parts of your aircraft, using modeling
grade polyurethane or epoxy paints. We recommend
UltraPaint one-step epoxy to best coordinate with your
favorite UltraCote colors. For good paint adhesion,
make sure the area to be painted is washed clean, dry,
and completely free of any oil or dust. When painting on
plastic covering, you may wish to dull the surface to be
painted with 000 steel wool. Mask the design with vinyl
tape.

NOTE: Before starting, it's a good idea to do s lay

out of the covering pieces you will need to
cut from the covering rolls, so that you
make efficient use of your material. You can
draw patterns on UltraCote's paper backing,
Be sure to leave a little extra material, so
you can go around the edge of the section
you are covering.

COVERING THE WING

Before starting, carefully read the instruction that come with
your covering.

You will cover the bottom of the wing first,

and then cover the top.

Set the covering iron to the proper temperature. Test it
by laying a small strip of covering over a scrap piece of
balsa and firmly pressing with the iron. Make sure the
iron is hot enough to activate the adhesive, but not so
hot that it bums the covering.

Using a fresh model knife blade or razor blade, cut a
piece of covering material at least 1" larger than one-
half of the inboard wing bottom panel.

Remove the protective backing paper and lay the cover-
ing over the bottom of the wing, making sure there is a
slight excess for wrap-around at the L.E., T.E.,and wing
tip.

When using UltraCote, work from the center out and
tack to the ribs, sheeting, and other wood surfaces,
using medium heat. Gently rub the covering with a soft
cloth to set it in place.
