Is this a CYA from Jeffco ? ? ? ? ? Bernie ---------- Forwarded message ---------- From: Josh Solis Subject: Jeffco Epoxy 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.
