Product details
Liquid 4-Liter Refill - Non-Hazmat, Non-Flammable & Non-Toxic Corrosion Block is a clean fluid that actively protects metal using advanced polar bonding chemistry. Synthetic additives in Corrosion Block completely penetrate corrosion cells, replacing salt water which is then allowed to evaporate. Corrosion Block’s hydrophobic film remains to further protect the metal and help prevent new corrosion formation.
