I'm building an F1/F4 utilizing modified RV4 wings. The joint at the tank/rib/spar is of some concern. The tank/wing splice doubler extends from top spar cap to bottom spar cap and offers some WX protection. It stops short of the spar cap for obvious reasons. This would be a water ingress point straight to the spar. I have ideas regarding sealing this area but would like to solicit more. Much thanks.
