Ethanol Resistant Resins

Hi there

I'm relatively new to using composites and not familiar with the different types of resins available. I am looking to make fiber glass petrol tanks for competition motorcycles. There are a lot of people already using these on the Pre65 Trials circuit but in the last few years a lot of them have started to delaminate and bubble. Additionally the resin has been clogging up the carburettors. This is attributed to the Ethanol in modern fuels.

Is there a resin available that is resistant to ethanol even at the quantities used in E85 which has yet to reach our shores.

Many thanks

Steve

I'm not sure but I seem to remember that POR-15, a common metal gas tank sealer works on epoxies too.
