Now I read up and for the most part people on here say its a waste of money but after my 04 navigators running boards rusted off (literally) and with illinois salting away at the ice in winter, I think I would like to do it.

I understand there isn't much in return but I've got a few spare cans of rhino liner from a one time job, a lift and a slow day at work so I would be wasting money not using up these cans. I would cover the gas tank, rear axle and exhaust is there any other spots I should avoid like and water drain holes or any spots in particular I should get. I'm aiming for mostly jut the frame and any body panels underneath. I'm not out a single penny one way or the other and I plan to keep this car untill the chassis rots through which I'm trying to prevent.

Thanks

Unless it's done before the car sees any miles, it can be beneficial. But after even a few 100 miles, the undercarriage requires prep unlike anyone in the industry that I'm aware of can do properly to provide proper prep. ANY and I mean ANY contaminants that are under the applied coating will cause more damage than if left alone.

The undercarriage of our Stang's include a number of plastic "pans" that require removal to access things, one being the fuel filter. Once you disturb the coating to get to the pins to remove a pan, you've defeated the coating.

I've driven northern winters for about 39 years and have had cars rust to crap; the worst being the ones that were undercoated post-factory.

Something can't be worse than nothing. Sorry for being doubtful but what you saw doesn't make a lot of sense. It's near spotless now as it is, if I wipe it down, just to get the dirt off and coat it with truck bed liner, I don't see how oxidation is possible, let alone leaving it open to salt and water and air being a better alternative.

If you are going to do the coating, don't forget the fuel & brake lines. Those suffer a lot from salt.

I Didn't know that. Thanks

I think it would be near impossible to get all of the salt and other oxidizing agents off before coating. you coat that with them in there and you won't know what happened until your foot goes through the floor boards...
