Reprofiling LS6 wings

Hi all,

Given that down the track I will need to refinish my wings, I am
curious about
the process. I understand that LS/DG will not provide profile
information to
allow accurate reprofiling of the wings. Is it standard practice to
just
reinstate the profile that the wing had prior to refinish? Has anyone
taken a
profile from another aircraft to use, for example using a later LS6-c
to
reprofile an LS6-b? What about using an LS8 profile on an LS6, since
they are
supposed to be the same forward section?

Thanks, Ben
