"print-through" of the fabric after painting is the resin continues to shrink
for a long time (i.e. months) after lay-up. So if your composite
structure is relatively "green" when you paint it, you're going to get some
print-through.
I concur with Scott's comments.
My plane was primered as I built it, so a good portion of
it was in primer years before final paint. The most recent primer work was
about 9 months before final paint. All areas of the plane showed the weave
equally after final primer and 320 grit sanding. So, I used another gallon
and re-shot the whole plane and re-sanded with 320 grit paper. Under those
dreadful fluorescent lights it looked the same. After the base coat/clear
coat paint and sanding with up to 2000 grit paper and buffing with 7 grades
of compound, under the fluorescents, the weave is still visible.
I'm pretty sure the finish on the plane is almost as
flat as Scott's (N92EX).
As I've said before, come and look at my plane……
with the fluorescent hanger lights off.
