Hi All,
I'm seeking advice about classic wings. Yesterday I was giving the wings a
once-over again before putting the remaining coats of smooth prime. I was
checking if anything else needed sanding. On the starboard wing, about 2
feet from the root and about 1 foot from the leading edge on the bottom of
the wing I noticed a small raised spot about 1 or 1 1/2" that was not there
before. I know, because I had already sanded it smooth and had two coats of
primer and had sanded a little of it back off, and was fairly satisfied that
all was complete. It appears for some reason that it has delaminated on this
one spot. I took my spline with some 120 gt and got it back level again
without getting into the glass. It still has some Super-fil on it. If you
mash on it, it gives slightly to the push in an area about 1 inch or so. My
question is; should I grind a big ole place out down to the foam, which
seems scary to me, and lay up a few plies of bid? Or should I inject (using
a big ole syringe I have) some pure epoxy through a small hole into the soft
spot? Or should I inject a little epoxy/micro slurry into the area and see
how it feels after it cures? There isn't anything in this area such as
controls tubes or wiring conduits or the like. I can't figure out how it
happened. The wings have been built for 10 years or so. I have kept them in
recent years in a vertical sling made of carpet connected to 2 x 4s, much
like the transporter. This is the only irregularity I have seen. Any
thoughts or advice you all can offer?
