Cab Floor Prep Guidance Request

I am looking for guidance on the appropriate prep for the installation of new floor covering in my 1974 F350 SCS, vinyl flooring.. (SoCal truck).
As one thing leads to another, I want to be sure that I take the proper steps to prepare the cab floor for re-covering. As this is a SoCal truck and has nearly no rust, I am looking for rust repair/treatment subject matter experts, to weigh in on what I should do to this flooring. It doesn't look like the floor has rust significant spots but maybe a little surface spots. See pic below.

Should I strip the paint that remains on the floor area in question? Then have better visibility to assess? or just apply some POR-15 over it and any other exposed metal areas then move onto the install the insulation and flooring, once completely dry?


I see no rust but a few bumps around the center of the picture.

Good paint will hold on so don't strip everything. As far as rust, almost anything that isn't smooth orange paint or black glue in that photo is some kind of surface rust. You need to hit that with a wire brush and ideally some kind of chemical rust treatment like phosphoric acid, then neutralize the acid. Paint over that with a quality paint of your choosing. If you're actually taking care of the rust probably an epoxy primer instead of a rust coating like POR15.

If it isn't any worse than what I think I'm seeing I wouldn't give it a second thought. at most scrape anything you think you see and hit it with rustolium or anything.

to each their own but I’d suggest stripping the entire area and treating with POR15. Being well versed with both this and paint, POR15 is a way better solution for what your dealing with. Wire brushing and spraying over what you have is going to leave a bunch of tiny uncovered areas that will be a bigger problem in a few years.
