Hi everyone looking to do some rust removal this weekend on my 4th gen, ontario roads are rusting up the frame. Wondering what are the best products or steps needed.

im going to buy a angle grinder and put a wire brush and clean up the surface as much as i can, and then im wondering what product i put after? what suggestions for the brand and how much would i need

What you see on the outside is happening 10x on the inside. I cut my frame in half and the inside of the frame was filled with rusted metal flakes. the flakes fill up the bottom of the frame tube, and hold in moisture, which accelerates the rusting from the inside out.

Fluid film is a popular one to slow down rust, so is diesel. But try to direct some inside the frame, thats where the real problem is.

Keep an eye around any brackets, pushing the area with a screwdriver to locate any serious problems.

Then buy a welder to get you an extra year.

Then buy a new frame

yeah, a lot of the frame rust on mine is surface rust, ive tried punching it with a screwdriver no holes. right now im just planning to wire brush all the visible rust off, so im looking for products to put on after i wire brush it, like do i just put on por15 only, or do i have to put a rust primer and then coat in por 15,

As others have said, the worst rust is on the inside.

yeah i realized is there any way to kind of remove as much of the inside rust as possible without removing the frame? like a wire brush to squeeze in?

I used por15 on my old Ford and it held up quite well.

I have used this product Loctite Extend Rust Treatment for years and is very effective in fighting rust especially living in CT. I actually took a paint brush and applied it in the inner fender wells in my 1966 Mustang back in 1996 when I bought it and no rust till this day.
