I recently looked at a glider that had been refinished by Dave Nelson in 2001/2002. It has been in it's trailer, and hangar for the last 2 years and not flown. It is located in Texas. In the dim hangar lights, the finish seemed a very faint yellow. Could of been all the dust... It was glass smooth, with no cracks or crazing, but when I used a flashlight, in the dim light, it "seemed" slightly yellow. I live in AZ, and have been told that once I moved it to a hot dry climate, it would "perk" up and whiten up.. Any further thoughts on this?

Thanks

Any 13 year old polyester finish can be expected to be a bit more yellow than when fresh. With some luck it will come more white when lightly sanded and polished.
Also note that some of these materials are a bit more "creamy" and not as pure white as others,
It won't bleach white in the sun.
Get it out in good light and look at it.
How perfect did you expect it to be 13 years later?
Good Luck
