Hi Bernard,
The manufacturer has not tested the material to see how well it works
with ethanol, so they do not recommend using it for parts that are in
constant contact with fuel or any material with ethanol in it. We do
offer a Jeffco epoxy tank sealer that seems to work well, p/n
09-42226. It is not a laminating epoxy, just a sealer, so the part is
made with a laminating epoxy, then the sealer is brushed on to protect
the part from the fuel and additives. I hope this helps.
Regards,
Josh Solis

A few years back I tested a small piece of aluminum plate coated with Jeffco by sealing it up in a canning jar submerged in gasoline with ethanol for a few months. Looking at it later under a magnifying glass there was no visable degradation of the coating. What I have read about its industrial application for being resistant to acids would suggest that it is very near if not chemically inert. It was nearly four years ago when I first used it in my wing tanks as the primary sealer. It spreads on application like an epoxy floor sealer...very easy to brush out.

We've used Jeffco 9700 Tank Sealer for many years with great results on aircraft running jet fuel to standard gas.

Biggest tip I can give is to make sure ALL pinholes and edges are sealed.

Jeffco 9700 is now Rhino 9700.(( Rhino of pick-up truck liner fame
bought them out.)) Google the manufacturers spec sheet and you will
find that it is a high quality cement paint with no mention of any
aircraft applications. I used it on my XP and found that after 13
years ethanol had almost completely dissolved it all away. I could
find no better material so I recoated my fuel cells with it again. I
keep a couple pieces of panel coated with 9700 in a quart jar filled
with MoGas. Every time I fly I give the jar a good shake. When the
coating on the piece in the jar gets thin I will know that it is time
to recoat my fuel cells.

BTW Rhino also makes a line of epoxy cements.
