Undercoating?

If you’re in any kind of salty environment, beach or couple times of year salt on roads areas, then I would fluid film at least once a year. Salt is what kills these trucks. If you get muddy a lot, then that debris can build up and hold moisture, fluid film makes it easier to remove mud clumps too.

 

Any good how to vids?

 

Ok, so I bought 3 cans of fluid film. Sprayed everywhere and every thing under the truck. I went heavy on some spots like nuts/bolts/welds, and light on some like the general frame area. Used my hand to "massage" it around.
Doesn't smell as bad as I thought/heard from people it would. Actually a slightly pleasant smell...
Ordered 2 more cans to get the front bumper area and couple other areas I forgot.
Good stuff!
