    Subject: Re: Pinhole leak in top of tank.
    Six or seven years since I re-Kreemed my fiberglas tanks, and they're still going strong without leaks or any other problems...and that's almost 1200 flying hours.

    Subject: Pinhole leak in top of tank.
    Thanks for the help guys. I'll be re- sloshing with thinned Kreem, and also hitting the area with epoxy, and also applying a thin sheet of aluminum and Proseal over the area. The last one was suggested and I didn't think it would look very nice, but I'll have to patch over the area anyway so it might be an idea.
