POR-15 and spray all metal parts with salt-x, this subject comes up every season. I pressure wash my truck and let it dry. After I spray about 2 gallons of SALT-X on the entire bottom side, including the engine, transmission etc. I also use a gallon of thinner mixed with one Qt. of oil and spray all of the suspension and springs. Both are sprayed on with a Hudson sprayer. When I get home I pressure wash the under side again and then run a sprinkler under it for several hours. When it dries I crawl under it again with a hose and good hose nozzle for another rinse. This usually required a couple of inspections and another rinse or two.
The next day I spray the entire bottom again with salt-X. This product can be purchased via e-mail
