KREEM may work for rust holes on steel tanks, but I and other people I know with '70s-era motorcycles have had no luck at all using it to protect fiberglass tanks from alcohol. The only thing that seems to work is Caswells tank sealant, a 2-part epoxy that I used two years ago to coat the tank of my 1972 Norton Commando with good results to date. The only credible stories of failure that I've seen with it were by people who skipped the rather rigorous pretreatment Caswells requires, which includes washing the inside with Dawn dishwashing liquid and water, drying completely, shaking the tank with acetone and drywall screws inside to rough the surface, drying completely, mixing and pouring the epoxy in a warm place, shaking it around, and letting it set, preferably baking at 140F for several hours after it sets up.
It may be true that Wicks PR-1422 would protect fiberglass against alcohol, but if it's made for certified planes there's no reason it ought to, because alcohol isn't allowed in fuel for certified planes.

I have had some experiences in the past with metal Motorcycle fuel tanks which rusted through due to poor maintenance, namely allowing water from condensation to sit on the botttom of the tank (for years appearantly.) While large leaks required welding to fix the problem, if caught early they are often fixed by coating the inside of the tank with an aftermarket product called KREEM TANK SEALER. It's available at many Motorcycle Parts Suppliers, and even JC Whitney, in various sizes for between $20 for a 16 oz kit and less then $60 for a gallon kit. I have a number of classic and antique motorcycles, and after treatment with this product have not had any of them develope new leaks after years of use. I usually use the cheapest gas I can find, and often it is part Ethanol, and seems to have no effect on the sealer. As a product that is specifically designed as a fuel tank sealer, it might be worth it to you guys looking for something that will stand up to Ethanol to research it.

It would be difficult to seal an ntire tank with it. I use proseal to seal my fuel sending units and he nut plates and bolts that secure them to the tank. However, if ou are not comfortable with the imperiousness of epoxy and glass anks to fuel, (I have found it is the pin holes that present the roblem, not the incompatibility of the matrix and the fuel) I would ecommend PR-1422 available at Wicks to coat the inside of the tank. t can be brushed on and is much easier to work with and can be used ith fuels containing alcohol (Of course there are many other reasons o stay away from alcohol, but that is not the point of discussion ere). PR-1422 has a shelf life for certified applications and Wicks ells the expired stuff for cents on the dollar.
