People on the KRNet make a fuss about using only vinyl-ester, but unless you are planning to run alcohol contaminated fuel, epoxy tanks really aren't an issue. I built my tanks with Saf-T-Poxy 20 years ago, then sloshed them with and alcohol resistant sealer. I have always run Mogas when I could, and for the last 4 years have been running mogas almost exclusively. I have never had an issue with the tanks or any degredation of the slosh compound in 20 years and well over 1100 hrs of service.
-Jeff Scott Los Alamos, NM ----- From:?"Ronald Wright via KRnet" <krnet at list.krnet.org> To:?KRnet <krnet at list.krnet.org> Subject:?KR> wing tank building material Is there any way to determine whether the wing tanks in an already skinned wing were built using vinylester instead of epoxy? A KR builder has a set of wings with Diehl skins already built. Older wings apparently off of what was a flying airplane, but NO information about what was used to build the fiberglass tanks? The wings are marked: 100LL ONLY. So, maybe they weren't built using vinylester?? I don't want to chance buying the wings without knowing what I'm getting!! Thanks, Ron
