Now in an environmentally friendly plastic spray pump bottle! We have improved Windlass Rustblocker by replacing the metal aerosol can with a plastic 16 oz recyclable bottle. You'll have less waste and won't have to worry about excessive heat or punctures causing an explosion. Fast drying and non-sticky, Rustblocker removes dirt and grit from metal and protects the surface for up to a year. Fight the high cost of rust with the same vapor phase corrosion inhibitors (VpCl) developed for the military and NATO. The metal-seeking vapors in Windlass Rustblocker form an invisible layer of electrochemical inhibitors that seal metal against the air and moisture. The easy spray-on application removes dirt & grime and seals bare metal for long-lasting protection. Perfect for all metal products including knives, swords, axes, firearms, or any metal part requiring cleaning and corrosion protection! Made in the USA.
