Hi All.
New member. I just purchased a very nice 2012 F250 Lariat w/ 6.2. Despite it being a midwest truck, the body on this thing is extremely clean (previous owner used it to pull an RV...I'm wondering if he didn't run it in winter...not sure).

My question is about re-rustproofing. The truck received rustproofing when it was new. You can see the plugs....no logos or identification on the plugs however (so I don't know what method was used). Given the condition of the truck, does it make any sense to re-rustproof?
I WILL run it in winter!

Thanks,
Trail

 

No, I wouldn't rust proof a 10 year old vehicle or reapply a second application. It can do more harm than good. I would only rust proof a new vehicle straight from the dealership before I even brought it home.

Frequent washing of the under carriage during winter is your best bet.

 

There are a few ways to look at this.

Rust ,oxidation, is more resistant to rusting than clean metal) ,however , if salt dust gets near iron compounds and moisture is applied either intentionally or unintentionally,it goes to work speeding up the rust cycle.. If we can prevent the salt from doing it's work, it might be worth it.

The cost is one consideration, as is the condition of the metal when the undercoating gets applied. Having seen what salt can do , to me I would do everything to prevent it's entrance or at least slow down it' effect. It is a personal choice.
