i have a 2013 with the rust module installed and trading it in for a 2016 XLT 302a. It arrived and the dealer is saying there is no need to install the rust module on the 2016. Curious what everyone else thinks?

 

I don't think these "rust modules" are very affective. The science behind it is sound, but I don't think they work as advertised. I realize these systems are installed on ships and whatnot, but I was a mechanic at a Mercedes dealer and have seen cars with these installed and they eventually rotted out at about the same rate as a car without. Undercoating is your best bet. I had my truck sprayed even though it is aluminum. As a mechanic, under coated vehicles didn't usually require a torch to unbolt parts lol.

 

If you can fit a socket over that layer of dry goo

 

Hahah yeah tar based crap is just that.... Crap. The best products are light and oily. I used Krown on my truck, fluid film is great too. Trust me, I live in Nova Scotia, the salt capital of the world, and if you don't spray your vehicle, it will turn to dust!

 

Known works very well. I was just there today talking to them about my new F150. They agreed that I don't need to do the body panels/drilling etc. For about $66, they will do just an undercarriage spray which is really all I want on the new truck.

 

It makes a huge difference if you live in a place where ther roads are salted in the winter. Money well spent.

 

Absolutely. I'm just west of Toronto and they use that brine crap on the roads all winter. Great for the roads and safety, but hard on the vehicle.

My 2010 was sprayed every year since new and had just over 100,000 km on it when I traded it. The frame and undercarriage looked almost new.

Thin, drippy oil is the only rust proofing method that works IMO.

 

Thanks for the information, my 2013 had krown so I guess will continue the process with the new truck.

 

Aluminum corrodes (oxidizes) as well mang. I'll let them drill holes in my truck as I mentioned before because that's the only way to get full protection. There are lots of tiny rivets used to put body panels together and foam used between those panels to stop noises and that foam holds water. Krown displaces that water, but to each their own!

 

my dealer did the say...no module needed...something how the frame to body joints had been treated.. so it would only benefit the frame/suspension-----said be better to just undercoat the steel...
