Sailplanes are white...because of gelcoat?

I believe the first Phonix was Polyester Resin, then the later models
were Epoxy Resin. Libelles, etc are Epoxy Resin....pretty sure.

The interior of the Libelle fuselage certainly looks like epoxy, but then
there's that opaque tan coloured layer just under the gelcoat on the
wings which made me think that maybe the wings were polyester. Could it
be some sort of sandable layer between the outside (epoxy?)/glass layer
and the gelcoat?

I don't know if B series are different in this respect: mine is pre-B
series and contains many m^2 of balsa.
