Hail damage - loss of value?

Actually they quoted about $1- 1.2k to reskin each control surface.
The 15k was to include reskinning, balancing, repainting all control
surfaces, filling very minor stuff on wings and fuse, repainting tops
of wings and fuse, new wing tips and stab tips.

But that 15k quote was preliminary.

Some of the bigger Beechs like bonanzas and barons have magnesium skins, and
these can cost around $6-8,000. Also, 10k for a quality paint job including
stripping, body work, priming, and repainting sounds low. Sanding and
painting over the old paint is not a good way to go, even though it might
look OK.
