TFLtruck has received this question.
“Guys, I have a question on undercoating my new 2015 F-150. I have emailed ford about undercoating and they didn’t reply. The dealer would love to do the undercoating job because of the money they make, but is it worth it? With the aluminum body they say no rust but aluminum corrodes. Will the undercoating help with the corrosion? I plan on keeping my truck for a very long time, 10 or more years. So maybe with your connections with Ford you could find out for me. Keep up the good work. Thanks Pete”
We are reaching out to Ford to get their take on it, but consider the following.
Exposed or raw aluminum does oxidize and can corrode. Think about patio structures, screen door frames, horse and other aluminum trailers, motorcycle engine components, some aluminum wheels, and more. Oxidation and corrosion will make aluminum appear cloudy, pitted, and otherwise degraded and eventually weakened.
However, the body of the new 2015 F-150 and majority of aluminum alloy wheels are painted. You should not have concern for aluminum corrosion unless your truck is scratched, dented, or damaged to reveal the aluminum alloy within. Just like exposed steel will eventually rust, the exposed aluminum will eventually corrode. You should repair damaged areas in a timely manner to avoid oxidation and corrosion.
Another area of potential concern are the points where the body and bed are mounted to the steel frame underneath. Ford spent the time to address this concern with coated bolts, clips, and isolated body mounts. The basic point is – you want to prevent the raw aluminum components from coming into contact with other types of metals or the environment.
Additional or aftermarket undercoating is not necessary after what we know so far.
