This rubber based brush-on liquid tape forms a protective, waterproof, UV-resistant, dielectric seal around spliced electrical wire to protect against corrosion, shortages, electrical shock and vibration. The quick-drying fluid cures in 24 hours and will not deterioriate or unravel like traditional tape. Resistant to chemicals, solvents, saltwater and other common fluids, to achieve connections that last for decades. To apply, shake well then use brush built into the cap to liberally brush the liquid over the splice/connection. Allow to dry for 5 minutes and then re-apply if a thicker application is needed. Ideal for both indoor and outdoor use and under extreme environments including automotive, marine, farm/ag and RV. 4 oz bottle Temp range: -30 to 200 degrees F and -34 to 93 degrees C
