Ken, That is very re-assuring that you are using Mogas with ethanol and your tanks are holding up. Are you positive on the Dow 511-45? I could not locate any reference to this on the web. Aircraft Spruce carries a Dow Derakane 411-350 PA Vinyl Ester Resin. Could this be what you used? Thanks for your help. Jim

About half of the gas I use in the summer and all the gas in the winter has ethanol in it here. Ken
Ken, Thanks for your input. Thats the experience that I am looking for. Does the Mogas used in your area contain ethanol? Thanks again for your help. Jim

Yes I have used the Dow 511-45 and also Hydrex 100 vinyl ester
resins without any problems in over over 1400 hrs of using Mogas.
