Shellac may be fine for coating cork that floats in avgas but do not use it for auto gas. I have a 1926 Disappearing Propellor Boat (from Canada) that uses a Kingston carb. Originally, the cork carb floats were coated with shellac which worked fine. Today's gas has many additives including some that dissolve the shellac. Then the float sinks and gas pours in through the needle and seat and overflows over the bowl and collects in the bilge. By this time the engine has stopped so you have to take apart your carb and put in a new cork float (if you have one). This all happens during a raging sea on Georgian Bay.The lesson is to coat your float with a thin layer of epoxy that is impervious to the additives (toxins) in today's auto gas. Never had a problem since.Jeff in beautiful clear warm TX where I've just cut out the ailerons from the wing.________________________________________________________________________________

Never had a problem since.I have had a bottle cork that I coated with t-88 floating in a jar with auto gas for over six months. Look at it periodically and have found no deterioration to date. And the cork is still showing the same displacement. Forwhat it's worth Don Hicks ________________________________________________________________________________

Can anybody tell me what happens if a cork sits in auto gas and isn't sealed withsomething? I'm tryint to figure out what would happen. Does it get sink eventuallyor come apart?DouweDouweblumberg(at)earthlink.net________________________________________________________________________________
