I have never found that sealing control surface gaps cures a flutter problem.
You are correct. Sealing gaps will not stop flutter. Doing so however,
will make the surfaces more efficient

Yeah I agree. I never seal them to stop flutter. I seal them to make the control surfaces more responsive. Also I do it to eleminate a gap caused by increased deflections (I fly 3D with max'd out deflections).
