Re: Help.... the ethanol in my gas ate up my doel fin... does it really do anything??
This wouldn't have happened if you used Stabil!
But seriously, the damage was most likely caused by the plastic fatigue due to road vibration while towing. You need a deflopperizer to keep it from happening again.
I would suggest repairing it, but that would bring up a bunch of bickering over whether to use poly resin or epoxy, when the clear answer would be to use Gluvit. Gluvit will microscopically fill in all the fractured (fracked) plastic and hermetically seal the pours.
