I just did my 2011 Ram 1500 Sport for the third time

Zero rust here in WI and I only drive the truck in winter - WI and the U.P. For snowmobiling

Fluid Film and LPS 3

Pull all the wheel well liners out - Spray through the factory holes in those double wall liners above the rear quarters

Backside of front fenders also where that strengthening epoxy coated patch is

Pull all the black plastic plugs in the rocker panels , and the cheap crap tape they used from the factory on the backside of rockers

I have never once seen this factory foam that everyone talks about anywhere in the rear quarters or rocker panels ? Even used a led flex light through all those tiny holes

Was this a specific year thing or a build plant ?
