Pro Form Copper Weld-Thru Primer

An anti-corrosive coating that has excellent adhesion and flexibility. Cold galvanizing when applied directly to dry metal, steel or galvanized surfaces, it stops rust by an electro-chemical action even in highly corrosive environments. Prevents rust creepage in the area of scratches unlike conventional primers. Apply to ferrous metals prior to welding to prevent corrosion and rust. May be applied after the weld for additional protection.
