From: Terrence O'Neill In-Reply-To: X-Original-Date: Sat, 22 Jan 2011 11:59:02 -0600 Content-Transfer-Encoding: quoted-printable X-Original-Message-Id: <96F5665F-B1D8-432A-9071-74C13F533AEA@charter.net> References: X-Original-To: "Lancair Mailing List" X-Mailer: Apple Mail (2.1082) This is a request for info on the possible similar experience of other = LNC2 builder-fliers... a wing tank fuel leak. The very slow leak through the front wing spar, when fuel leveel is = above about half way up, is of course uninspectable because of the = leading edge -- and further because it is possibly behind the root area = secondary web ... not to mention the fact that the spar web is sandwich = construction and the interior skin leak can propagate spanwise to = another portal in the forward web skin. So my question is, when I slosh-seal the tank, what is recommended as a = prep for the tank inner surface? I've read MEK and another TankPrep stuff. For sealant I've looked at PR-1005-L, and at the automotive (supposedly) = stuff, and phenol novolac. Any suggestions soulfully appreciated, for this worrisome job. Thanks. terrence N211AL LNC2 235/320.
