I suggest trying to reglue the joints 1st, then if need be glass over
the area AFTER you have stripped it down to bare wood (or fiberglass).
Do the stripping by sanding - DO NOT use zip-strip or something similar
as it will leave a residue in the wood you will not be able to get out
and the residue will play havoc with the resin within a short period of
time.
Remember, the glassing IS going to add weight, plus you will need to
rebalance the plane after everything is finished.
Before thinning the resin, try heating it with a heat gun 1st. This
will USUALLY thin it out satisfactorily.
If you insist on thinning the resin, ONLY USE acetone OR denatured
alcohol. In any case I suggest thinning 5% BY VOLUME AND DO NOT EXCEED
10% by volume.
The thinning is going to weaken the resin, however the weakening with a
5% thinning is minimal. Also, be aware it is going to take SEVERAL DAYS
for the resin to set up (cure), AND the resin is going to be very soft
for an additional 7 - 10 days.
