Graupner Stabilit Express will firmly adhere anything to anything else. It is unsurpassed for joining such critical things as a nylon bellcrank to a fiberglass fuselage, or metal or plastic tubes to plastic or fiberglass. It is a two part methylacrylic adhesive. One part is a thick liquid, the other is a white powder. Included are a mixing tray and measuring spoon to give correct proportions. After mixing, the material sets in only 20 minutes into a wood-colored mass. The fully cured material can be sanded and finished. The cured material has both compression and tensile strength, so it can be used as a structural element in addition to simply bonding other structures.
