Troy,
I am not expert, having only build one aircraft, but it is was mine I would
remove the whole area and re glass. You can find spots that are a potential
for delaminating by bouncing a coin on its edge over any suspect areas, it
will sound hollow if it has de laminated. Now is the time to find all these
spots rather than after its painted.
Just my 2 cents worth.

Subject: Europa-List: Classic Wing Repair Needed
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?
