Composite-ARF YAK 55SP (3m span)
have been missed.
When sanding areas on the inside of the composite sand-
wich parts to prepare the surface for gluing something onto
it, do NOT sand through the layer of lightweight glasscloth
on the inside foam sandwich. It is only necessary to rough
up the surface, with 80/120 grit, and wipe off any dust with
acetone or de-natured alcohol (or similar) before gluing to
make a perfect joint. Of course, you should always prepare
both parts to be joined before gluing for the highest quality
joints. Don't use Acetone for cleaning external, painted,
surfaces as you will damage the paint.
Tip:
For cleaning small (uncured) glue spots or marks off the
painted surfaces you can use old-fashioned liquid cigarette-
lighter fuel, like 'Ronsonol' or equivalent. This does not dam-
age the paint, as Acetone and many other solvents will, and
this is what we use at the factory.
At Composite-ARF we try our best to offer you a high quality kit, with outstanding value-for-
money, and as complete as possible. However, if you feel that some additional or different hard-

cleaning small marks, clear wax,
uncured glue, or similar off the
painted surface of the plane -
without damaging the paint.
