12 oz. Smooth Catalyzed Filler (polyester)
Really a great product for filling the voids in glass fuselage, tail fillets and under or over primer coat.
Easy to dispense in small quantities will cut down on you Bondo waste significantly. Fairly vicious so it fills pin hoes and soaks into small voids. Drying time can be adjusted from 2 to 20 minutes depending how liberal the hardener dose is.
