Yes, sanding and drying off with a clean moist towel. We want a good grip for the second layer so we are following procedure.
I tought it was common practice to always sand now, even after using peel ply. Wasn't it discovered that peel ply wasn not sufficient to give a reliable secondary bonding in the experimental aircraft hobby?
We are definately using glass intended for use with epoxy as we are probably ending up with a clear finish to begin with.
Any toughts about the peel test?
