Re-curving mylar on a glider

Same thing happened to a Ventus B a while back on the
elevator. Since I fly a Ventus B and I fly it in AZ
I have decided not to use external seals on the elevator
at all. It is internally sealed. My wings and rudder
are internally sealed and both sides of the rudder
have mylar however only the bottom of my wings, flaps
and ailerons, are externally sealed. I have found that
I do not have to replace the bottom seals very often
+5 years, but the tops I would have to do every year
in the AZ sun and that is flying every weekend form
March through Oct Friday thru Sunday putting it away
for the weekdays

I think there was at least one Grob crash in Germany.
Some manuals
specifically state there has to be tape on the elevator.

So, yes, this is a serious issue. Since hearing of
the first crash,
'check condition of mylar and hold-down tape' has been
part of my
critical assembly check.
