It cures to a durable, elastic rubber that bonds well to metals, plastics, and painted surfaces. Truck and trailer technicians commonly use it for sealing seams, joints, and roof repairs, or for bonding body panels where a strong but flexible connection is needed. Trucks and trailers are exposed to constant vibration and weather, so non-sag, UV-resistant sealants like this are used to keep water and corrosion out, replacing dried, cracked caulk.
