My tank sits high off spar due to dimple-countersink. I was not the one who countersunk the spar. I have built the tanks. Dimpled the tanks for #8 screws, ATS dimpler. The tank skin bulges .024 off the spar between the screws and .011 at the screw. The tanks fit, but does not leave a clean line at the tank and main wing skin. In other words, the spar is not countersunk deep enough. Is there anything I can do now to correct this? Thank you for your time and thoughts.
