Trunk Surface Rust....

[MoparThomas]

Pretty big area, was just going to do Rustoleum Rust Reformer on it, but wanted a few thoughts prior to moving forward...

Wire brush a lot

Look like a molasses soak could be good for that as it's in the recessed area just have to make sure the car is level. Seen some good results on here with it.

Do not be surprised if it looks like a screen door when you are done brushing and scraping.

Wire brush it as much as you can to remove the surface rust, vacuum it with a shop vac, then wipe it down thoroughly with a good degreaser. Apply 2 coats of POR-15 per the container's directions.

What pnora said is true, if that rust is more than just surface rust, you might need a new trunk floor; even POR-15 is only gonna be a temporary slap-'n'-dash fix.

I used Corroseal converter on some surface rust on my floorboards a few weeks ago and was pretty impressed with it. At least you can witness it doing something as the white liquid turns the rust pitch black. Whether it really stabilizes rust long term

Either molasses soak, or por-15 is what I'd do. Mechanically devouring the sheet metal may leave little remaining.

i’ve been experimenting on rusty stuff w molasses, 10-1 ratio . it definitely works !!!

Looks like a human face is in there.
If you stare long enough at it

I've had good results with Corroseal rust converter. As others mentioned, how much metal is really left? You won't know until you clean it thoroughly.

I would wire brush the area fist, then vacuum the area. Go to Home Depot and get a gallon of Klean-Strip Concrete and metal Prep.
It contains Phosphoric acid and dissolves rust and etches concrete. Here are some pic's of my trunk floor. I had a few pin holes so
I soldered them shut and then used a few coats of Epoxy primer. after that dried I followed up with two or three coats of G-2
Evercoat high build primer. I used a 7/16" wooden dowel rod with some sticky 80 grit DA paper to get the grooves smoothe. Keep priming and keep sanding!
It looks "Mahvelus".

If you have some pitting you want to hide, I’ve used 3M structural panel adhesive epoxy and squeegeed over it and sanded it out. I like to think it added back some of the strength the pitting took out.
