Aircraft Covering

Varying temperatures and storage delays can cause covering material to loosen over time and
transportation. We recommend lightly going ov er all the co vering with a covering iron set at
medium temperatures. Be sure to use a soft cover over your iron so you do not scratch the covering
surface. Be sure you go over all seams and edges of the covering to assure it is secure to the airframe
