Anyone had experience with these rust prevention products? - PeachParts Mercedes-Benz Forum

These are generally well reviewed, but I'm interested in hearing if others have personal experience OR alternative suggestions from another supplier.

I have used POR-15 a few times and would like to try another line.

Spray can with extended nozzle/hose to reach inside frame sections, thinking specifically of the rear of a w123:
Internal Frame Coating w/Spray Nozzle | Eastwood

And this one, thinking of painting the trailing arms:
Eastwood Rubberized Rust Encapsulator Undercoating - Black

I understand you feelings about Por15..
very hard to apply according to specs..

as to inside a cavity.... might look up Fluidfilm ...
this is sold by Farm tractor sellers... maybe also marine parts stores..
straight lanolin ...sheep oil .... no sheep are harmed in the process of milking them...... no real problem with application ... but would need to be reapplied once in a while depending on condition....

Yeah, I didn't want to get into it but POR-15 has to be the most noxious stuff I have ever dealt with. I had to trash the Tshirts I wore doing my wagon floor, afterwards, the chemical smell wouldn't come out in the wash. My neighbours thought I was nuts, wearing a respirator working on car floor.

I agree 110 percent on Fluidfilm, I used it last fall for the bottom of the car and inside the doors and under the hood.

However, for stuff like the frame sections, I don't really want to go through the exercise every 12 months, and when I read the material on FF that is all I believe they guarantee for adhesion overall, and less than that for undercarriage work. No doubt FF will likely last much longer inside a closed section, of course.

What I actually wanted to do was apply the inner frame coating, then FF after it dried. Sort of double indemnity.

For the trailing arms, the seams are rusting now so I am keen on getting some sort of rust-stop/encapsulator on there. But for sure the underside then gets a FF bath next fall.

For seams already rusting....
hard to beat... but hard to do correctly .... paint stripper .... power wire brush.... Metal Prep ...
good epoxy primer ... good matching epoxy paint... .
follow all can instructions..
and you will still need personal protection...
but Por15 is over the top for all the things you mentioned..... and if it only sticks to parts of the item.... really hard to get off to redo....
I was pretty careful on my bushhog mower ... it lasted a couple of years.... but not the bullet proof covering it gives the impression of being...
and this was not an impact area I used it... only one under the pto shaft where grass sits .... flat... no impact... only a couple of years... good regular paint lasts just as long there....
