COVERING
The following ironing procedure is for the World Models Tough-
Lon covering. Please follow the instructions included with the
covering material. Please completely remove dust from the
surface before covering, or the covering will not stick to the sur-
face. The covering adhesive is activated at 58ºC/136ºF, and
shrinking starts at 90ºC/194ºF. Set your iron at about 60ºC/
140ºF to begin.
Lay out the Fuselage coverings.
Cover iron with cotton cloth to eliminate scratch and bet-
ter temperature distribution. A hobby grade sealing iron
with cover sock is recommended for better handling.
Take out the covering piece for the bottom of fuselage,
and peel off backing sheet.

Place covering on fuselage bottom, completely covering
the surface with 5mm overhang at all sides.
Tack the covering at corners, this will temporarily fix the
position of the covering, and start ironing on the covering.
If position is not right, apply heat and peel off the covering
and rework. Never try to peel off covering when the co-
vering is cold and adhesive has set, you may pull away
wood or separate the color layer. Always heat up the
covering to melt the adhesive before peeling.

Iron on the overhangs to cover the edges. If you need to
shrink the covering to conform to the shape of edges, you
can do so by raising the iron temperature. Just apply heat
at the required spot only. Since the shrinking temperature
is much higher than the adhesive melting temperature, if
you apply high heat at area near the edge or seams of
covering, the covering will pull away from the edge or
seams. Trim off unwanted material.
