1-26 corrosion humid environments (was first glider)?

I had been browsing 1-26's looking for my first glider and had a few
sellers tell me the 1-26 would not be happy in Florida due to the
humid environment.

Is this because the fuselage frame is made from steel rather than
aluminum and prone to rusting?

I know there are plenty of 1-26's here in Florida and I had never
heard of this problem until now...

But, in case you are wondering, I have decided that it may be better
to save another $6K and get something with a 30+:1 glide ratio than to
try to sell the 1-26 later when I am ready for something with better
performance. Laying in bed I realized that 20:1 glide radio is only
twice that of a Cessna 172! Ouch. Ultimately I would like to fly
cross country... I tend to get bored flying around the airport.

I admit I am attracted to the "one class" and simplicity of the 1-26
so I have not ruled it out completely... decided I will keep saving
money while trying to decide, however, the closer I get to $16,000USD,
the less appealing the 1-26 becomes.

Thanks
