block in preparation for feather fill. A spray or brush coat of
feather fill will build up .02" to .03" thick, fill the glass weave
and any medium sized out-of-contour spots. Feather fill will require
several hours curing time before it can be sanded. The cured feather
fill is sanded to contour using a spline or soft block and 100-grit
sandpaper. Again, extreme caution must be exercised not to damage the
glass structure in pursuit of a good finish. The contouring must stop
immediately when the highest glass peaks begin to be visible as the
feather fill is sanded away.
..... If you find that you have underestimated the fill required or
just have a thin coat, don't hesitate to use a second coat of feather
fill. A well prepared surface generally won't need more than one
coat. When you have finished contouring the feather fill, the surface
should be basically smooth and fair. The primer to follow is not
intended to be contoured heavily, just smoothed with finer sandpaper
for a smooth finish while leaving a substantial ultra violet barrier.
..... After you have filled and contoured, re-inspect for sanding
damage; it is an easy thing to do! Remember, you are only allowed to
sand into the first skin ply in local areas no greater than 2 inches
in diameter and all of these areas must total less than 10% of the
surface area. Wherever there is only one ply, or where the UNI cloth
is crossed for strength (e.g. the canard and wing skins), no sanding
of the ply is allowed, except for "scuffing Up” the surface. Be
Careful!
