This left the Hysol unsealed and exposed to fuel...>> Unless I have some misunderstanding about what you are describing, they are all like that. As per the construction manual (ES - Chapter 10), the Jeffco 9700 tank sealer is applied before the wing is closed. The Jeffco 9700 Sealer should be brushed on so that there is a very slight overlap of sealer and Hysol to insure that all the surfaces are covered by Jeffco 9700 except for Hysol squeeze bead. I think I remember the manual calling for something like a 1/4" or so overlap. The Hysol squeeze bead that you should have along the edge of the bond joints will not be covered with Jeffco 9700 unless you go beyond what is called for in the construction manual, and access provisions are made, to apply Jeffco 9700 over the Hysol bead. There should be very little, if anything to be gained by doing that. I would swear I remember reading somewhere that Hysol 9339 is fuel resistant, but I can't remember now exactly where I saw that. As long as you do have the access, it would not hurt to inspect the bond joints and make sure everything is sealed well. If you see anything that looks like it might be questionable, you might want to address that. ------ Don Parsons Houston, TX DAP@Lancair-ES.com http://www.Lancair-ES.com/ ES-166-FB / N198TD (Reserved) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://members.olsusa.com/mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please remember that purchases from the Builders' Bookstore assist with the management of the LML.
