Preparing glider for storage

For three years, it might be worth taking your glider with you! This
may not apply to Antarctica, Iraq, or a few other places.
Since you used the term fibreglass, perhaps it's not registered
Experimental, so easy to register elsewhere.

If you must leave your glider behind, coat the lift pins, spar
pins, L'Hotelliers, etc with a rust inhibitor like LPS-3 or Boeshield.
I've had decent luck using a modified "mole chaser" to keep out
rodents. Remove the device from it's original housing, mount it in a
project box with a voltage regulator on the incoming power. Use a 12V
glider battery and a solar panel to keep the thing running. Leave it
somewhere in the trailer that will resonate nicely.
Waxing is good. Don't forget the trailer.

Or you could lease it to the fellow a few threads ago...
