if my tanks were done in 2010 does that mean i shouldnt worry? because it has the good resin.... the tanks were done at skater. i run 87 octane with my 300r motors and it has ethanol in it

If the tanks were somehow fixed at Skater in 2010, they most likely did the vinylester resin job to make them ethanol proof.

I can’t imagine that anyone needed their tanks fixed for any other reason than ethanol damage.
