This is an excellent covering choice for lightweight park flyer models to large,
scale models up to 80”. It weighs about the same as SG Silkspan, however, it is
much stronger and more resistant to puncture damage. It can be applied using thin
clear Nitrate dope as an adhesive and can be finished, on lightweight models, with
as little as one coat of clear. Two to three coats of clear Nitrate dope will completely
seal the surface on electric models of all sizes. Other water based products are
A major difference between Polyspan and tissue or Silkspan is that you can remove
wrinkles before or after covering by simply applying heat near the surface. Polyspan
is unaffected by water, moisture, or humidity. It spans open structures perfectly
and is intended for both solid and open covering. It replaces ½ ounce fiberglass
as a lighter and stiffer covering option on sheeted surfaces. The only major working
limitation is that it doesn’t go around complex curving surfaces as well as other
materials such as tissue or fiberglass. Sold in 48” width material for less waste!
