The original airfoil design and the resulting profile when produced at
the factory probably are not the same. They may be reasonably close but I

relatively new sailplanes.

Sounds to me like one more reason to start with templates of the original
airfoil. Or would you prefer to rely on the profile not replicated exactly
by the manufacturer and later modified by a refinish shop that produced less
than perfect results?

As the original poster is talking about refinishing the leading edge only
differences shouldn´t be that large.
