The Corrosion Solution CORSOL® corrosion solutions are used to protect our steel components that need it the most from the devastating effects of corrosion undercutting and blistering. The PRP® Industries’ METAL POLYMERIZATION process utilizes strategically paired chemicals andprocedures, resulting in a finish guaranteed not to undercut and blister.

Field-Proven TestingWashington State Department of Transportation is particularly hard on its snow removal equipment. Exposure to months of harsh conditions and corrosive road salt while operating in mountainous regions is why we chose their equipment to field test CORSOL® corrosion solutions. The two salt spreader trucks shown below were brand new in 2008 and have since operated continuously out of the same facility.
