I was looking for anti-corrosion spray to protect my snowblower yesterday and came across this Fuild Film spray. Some people suggest to use this for the truck frame and underbody as well. I've seen pictures of 392 underneath with rust started developing, so I'm wondering if any of you know about this product or any alternatives to rust proof the underbody and the muffler as well.

Have used Fluid Film for years.. always impressed.. and never any issues.
Generally I apply it in the fall every year .. 3 cans will do the whole underbody and in the frame rails as well.
They make can attachments for getting in the frame rails.. but I have never used them

Living near the ocean, this is definitely good info to have. Appreciate the feedback!

Thanks, great to hear! Do you also apply to the break rotors? The new rotors I got for my Grand Cherokee started rusting in a few months even though it parked in garage for most of the time. I blame the dealership for not using good products because my wife's Audi has not shown rust in rotors even after a few years.

Especially these two areas of the rotor from the attached pic that I found online just to describe.

Have never done that no. Pretty much everything except wiring and anything that gets hot.
Theres a couple good youtube videos about it

If fluid film is petroleum based or has silicon in it, just be careful doing the rotors... :oops:
