Crevice Corrosion and Pack Rust are the cancer which is destroying our steel infrastructure from the inside out. Conventional film forming coating systems do not have the active chemistry which can effectively neutralize the corrosion cells which cause crevice corrosion and pack rust. They just cover up the problem. This is why the joints and connections coated with conventional systems bleed out so quickly after coating.
The photos above show crevice corrosion and pack rusted joints and connections which were coated with conventional 3 coat systems bleeding out after one year.
