I live in a New England state, close to the ocean, and downwind from factories sprewing acid rain. That with all the ROCK SALT they dump on the roads....Well my 2001 has rust underneath it already.
I've purchased a 2002 F250 from out west where they don't have rust.
I'm thinking of having it undercoated. I'm reading that Line X has the best reviews for the truck bed, but what's the groups opinion of spraying Line X on the underside? Does anyone have any idea what it might cost?
I don't know about the cost, I'm guessing under $500. But the company that did my liner, had told me that they have done it as undercoating. I think its a great idea, prevent rust, and help with road noise. I would call the line-x dealer close to you, or take it to them, and ask them.
