B12 is our most popular aircraft stripper and better suited for more fragile metals like zinc, magnesium and delicate aluminum parts. It has a spray viscosity and can be plastic wrapped and left on overnight. B12 has also been proven effective in marine restoration for removing anti-fouling paints that are used below the water line on fiberglass hulls.
