Corrosion is a nightmare! To do it correctly requires the use of very expensive, short shelf life materials which will expire before completely used. No more! We have developed an inexpensive solution! Phosphoric acid has long been known to disable corrosion at its source. These single-use applicators contain enough metal cleaning solution to treat a typical pinchweld, but are packed in sealed, single-use applicators, keeping the material inside fresh and ready to use. Includes lot code information to include with your urethane manufacturer’s warranty registration.
