I have the early 90's fiberglass tanks that were Kreamed. They have never seen Ethanol gas and the Kream appears as a very thin whitish coating on top of the light tan fiberglass. I don't have any delamination of the Kream (yet) and no gobs of resin, though my tanks have only seen a couple of years with fuel. During the annual condition inspection I pull the finger strainers and inspect the tank interior but have found no loose material in them to date.
