The experience I have had is that the S-Glass is used as an
external scratch layer as well as strength. It can be sanded and
repaired if one scratches into it. Kevlar on the outer layer is
extremely difficult to repair cleanly as it fuzz's. I'd be tempted to
use the same weight E-glass. I have not read this book so I'll add
this. If the design is 2 or 3 full layers and no partials I would
think about either kevlar of E-glass partial layers in the layup to
add stiffness where needed.
