end without trapping air. Larger designs (such as
sunbursts) should be positioned and the narrowest end
tacked in place. Then,
working towards the wide end, iron
the design down. Pin striping, etc., can
be made by cutting
®
thin strips of ORACOVER . To apply multicoloured
patterns onto a fuselage in open frame structure or a wing
(open framework structure), iron the single patterns on the
backing paper on a flat table together. The iron should
have a temperature of approx. 80 °C. Allow for a 1,5 cm
overlap at the seams. Darker colours should always go
over lighter colours, so that the edges of the dark colour do not show through the lighter
one. Pay attention to accurate positioning when ironing on. When ironing the pattern on
do not heat the seams of the pattern too much - the heat could melt the adhesive and
shrink the seam. If you use a heat gun protect the seams from overheating using a
cardboard template, if applicable.
PATCHING and So that the patch bonds well, be sure to remove all traces of engine oil and exhaust.
REPAIRS For a simple tear or puncture, cut patch 0.8 to 2 cm larger than the area to be
repaired. With the iron set at low heat, apply the patch directly to the clean surface. Or
for a neater repair, carefully cut out the entire bay and apply a new patch with a
minimum of ½ cm overlap.

HEAT GUN ORACOVER will shrink to the surface with the use of a heat gun and will appear to
have covered it well, but it will not have bonded to the surface. If you are using a heat
gun for final bonding, follow Steps 4, 5, 10 and 10a for proper tacking. Use the heat gun
®
to shrink the ORACOVER over open framework as in step 8. Over sheeted areas,
®
heat the ORACOVER and using a 100 % cotton rag, quickly rub the heated area of
®
ORACOVER . This rubs the adhesive into the wood for a solid bond. Be sure to do
small areas at a time. The finished effort is well worth the extra time.
®
SCALE and ORACOVER SCALE and CHROME have an aluminium layer of only nanometres'
CHROME COLOURS thickness on the backside of the covering film. This layer is designed to maximize
colour density and quality. To minimize the RF shielding effect of the covering on a
®
fuselage covered with ORACOVER SCALE or CHROME we strongly recommend
leading the Rx aerial out of the fuselage by the shortest route and running it out to the
leading edge of the fin, or use a whip aerial. The same applies to wings covered with
®
ORACOVER SCALE or CHROME: Do not run the Rx aerial along the wing as this
too may cause a loss of signal. Always make sure that the Rx aerial has an open
destination field. We recommend you follow the same procedure with models
constructed from carbon fibre.
WOOD and MOISTURE Please be aware that wooden model structures absorb moisture and swell in warm,
humid conditions and contract under cool dry conditions. If you build and cover your
model in humid conditions and then later the weather changes to cool and dry; the
covering film tension will decrease as the wood releases moisture and shrinks. In this
case you will need to re-iron the covering in order to remove sags or wrinkles.

We would appreciate your comments and suggestions regarding ORACOVER and its applications.
PLEASE NOTE: Recently, more and more model aircraft with styrene foam wings have appeared on the market. To
reduce production costs in many of these models pre-dried foam is no longer used; instead foam containing a
relatively high residual moisture content is used. To ensure this moisture stays inside the foam we recommend you
®
create a moisture barrier by applying a thin coat of ORACOVER -iron-on adhesive (ref. no. 0960). Allow to dry
overnight.
