Protects metal surfaces. The 95% pure zinc cold galvanizing compound electro-chemically bonds with metals to stop rust creepage and corrosion. Sprays or brushes on cold. Heals itself when scratched. A coating of Galvax is comparable to hot-dip galvanizing for metal protection. Cures damaged hot dip coatings and repairs damaged galvanized surfaces. Used for welding touch-ups and spot-priming.
