I've got an F350 and I take it down to the beach regularly. Its an 2005 so most of the factory rust protection is gone, and despite washing it off religiously right after i get back, I am quickly developing a rust issue. What can you guys or gals recommend to degrease the under carriage, clean the rust off, and coat it with? I talked with a body shop guy and he recommended a spray on rubber coat, but I don't think he know the amount of abuse this truck gets. I KNOW you all understand. I looked for a place that would do it but 1)i want to make sure it is done right and 2) there weren't any places around houston that jumped out at me. I appreciate any suggestions. Thanks!
