RE: REFLECTOR: Fuel tank sealant

Gordon, I have used Jeffco 9700 in one tank so far (plus the central tank).
I bought the 3 gallon kit from Aircraft Spruce (page 259 in the '98 catalog
-- Indexed under Fuel Tank Sealer).  It looks like I have well over 1/2 the
kit remaining for my final wing strake.  My experience on the sump (central)
tank was a perfect, air-tight seal with 2 coats plus a few dabs of overkill
where it looked like it might have pin holes.  There was a short article in
V V on this.
Likewise, I used 2 coats on the strake tank plus a very thick cabosil
mixture for the top-strake to bulkheads sealer.  The Jeffco took a lot of
cabosil before thickening enough to bead well on the top of the bulkheads.
I have not tested this tank for leakage yet.
The second coat of Jeffco needs to be applied less than 20 hours after the
first to get a good chemical bond.  The Jeffco will exotherm quickly if left
in it's mixing cup but it flows well for about 15 minutes if spread on the

        I cannot seem to achieve a smooth shiny finish in my tanks, even
using cab o sil, and allowing the mixture to "age" in a shallow pan before
application.   I recall a past thread concerning s sealant called Jeffco.
Is this the Epoxy in the ACS catalog?  What amount is needed for a Velocity?
