I’m looking for gasoline-safe fiberglass resin to fix a weeping fuel drain in my right tank. Can anyone recommend a product I can use?

i spoke with Heather and Brandon at Kitfox, they suggested I drill and countersink the existing drain hole, fill it with resin mixed with milled glass fiber, cover it with a few layers of resin and glass cloth, then drill and tap a new drain hole. All I’m missing is the resin to make the repair. Brandon suggested polyester or vinyl-ester resin, but I haven’t found a product yet.

I found Bondo resin at the auto parts store, they even have some with the milled fiber already mixed in. Will that do the job?

Thanks,
Jack
