Where can I get a job like that? I'd love to have a job where I can abuse other people's airplanes for money

I must agree with the general sentiments on this subject:
1. GP is not asking anything unreasonable.
2. Send only the parts that failed or need replacing in, unless the airplane is totaled.
3. Send the parts in! GP is not a cruel, heartless organization. If the damage is not obviously pilot-induced, then they will replace it. When I say obviously, I mean OBVIOUSLY. There has to be tire marks or boot prints on the covering, or something equally incriminating.
