Today I cracked out the flap I covered yesterday. I then checked the wash out !!!! GULP !!! well It has some washout but not as much as described in the manual. I rang Andy at Europa, and after some time talking to him and measuring and rocking the flap, we came to the conclusion the it would be OK, ( We Think)I decided To laminate the STBD flap top skin. It is setup as before, and the layup as above. I hope that both are the same.
