    Default Unopened, expired, Poly-Brush

    I have two gallons of Poly-Brush that I got with my kit, but I won't be covering for a few months. They expire this month, August. Has anyone found a use for expired Poly-Brush?

    If the stuff is factory-sealed then I wouldn't be surprised if it's just fine. I would call Poly-Fiber and ask them before ordering more. Be sure they understand that you're asking about an Experimental airplane.

    I have used poly brush that was way, way past it's supposed shelf life. Just did last week in fact on a set of Kitfox 4 wings that i just recovered. All is fine. JImChuk
