Stopping (or slowing) rust on a 6 year old truck?

[Appleboy84]

Ever since we bought our 2013 Silverado, it never had any aftermarket rustproofing products. At the time, I never thought about it. But, as I learned more about trucks, I started to thing about rust proofing. Now, I live in a place that does use a lot of salt in the winter. Being that this truck is 6 years old, it does have some surface rust on the frame. Could I still use rust proofing products in my case? What would you recommend? Is it possible to remove this rust, and then apply it, or could I just put it over the rust?

Once the rust has started "rust proofing" does little or nothing. There are several rust inhibitive out there, POR-15 is the only one I have any personal experience with and I am very pleased with the results so far. It's been almost 2 years now and still looks like the day I got it done. I did all the work myself its not hard but it is time consuming, drying/curing time is pretty long. I had 6 days in mine but I did both frame rails inside and out except for behind the fuel tank and all the cross members and rear end housing.
