Select the main spar, remove the peel ply etc, prepare in the same way as for the
rear spar. Place in position on top cladding (center of top liner coincides with BL 0), locate
and mark all bonding surfaces including rib positions. Make sure all surfaces are free of
any peel ply and other particles. Leave rough surfaces for gluing with 50 sandpaper.
