Blistering of Finish

Having observer the shrinkage in a 5 year old ASW 27
and 28, bear in mind there are no perfect 30 year old
gliders. put the wings in a plastic tent for 2 weeks
with a dehumidifier and the blisters will probably
disappear.

although i prefer gelcoat for repairability, in strong
uv conditions automative paints last longer, it is
quite possible that nothing much will happen to the
LS3 for 10 to 15 years

I have 1 glider which lives in cool and damp conditions,
the fuz was sprayed with paint 20 years ago after a
major repair , mostly over gel, no primer, still there
with a few blisters. Another, part but not all of the
gel was removed fom the tops of the wings and a thin
coat of new gel applied, 10+years ago. the old stuff
shows at the edges, but most is shiny and white (I
have regelled lots of other bits of the glider, some
bits have small blisters after a year, possibly because
the gel is to thin).

sounds like you have an honest seller, you have to
be realistic. gusssing the price range you will spend
a lifetime looking for the perfect glider

I'm looking at purchasing an LS-3 but the owner has
noted that the Urethane finish has blistered in several
places on the tops of the wings (The glider was re-finished
in 1996). According to the owner they are very small
blisters which have left pin sized holes. I'm assuming
that this would be caused by mositure which has made
it's way below the paint? He says the trailer is dry
and has a soler vent so I would assume humidity in
the air has caused the problem? and not moisture on
the surface.

What are the implications/underlying problems of the
blistering? and could I fix this easily or am I looking
at sanding down/re-finishing the entire surface of
wings again in the near future?

Any advice would be appreciated.
