Tips for fighting rust

[Maximilian55]

So I recently bought a 85 4runner. The only issue it has is several spots of rust on the body. I'm stripping the entire thing down to fix dents and repaint. I'm considering trying out rust converters like por 15 to make the job easier. Does anyone have experience with por 15 and any rust removal products I would appreciate any advice.

POR 15 and a similar product, Chassis Saver are great for rust that can just be covered up, like on the frame, under side, or under carpeting. I've never used it but I saw a chassis treated with it and it looked great and had a durable finish. It is only to be used on rust, it won't bond with the metal otherwise, and it is reactive to UV light. If you're doing body work, you might want to go another route.

Eastwood Internal Frame Coating is awesome stuff, works great.

How to fight it? Cut it out and weld new metal.

Frames rust internally. Surface rust isn't as big of a deal compared to areas where debris, salt, mud and water can sit, like inside the frame Outside of that, POR15 is good stuff, but so is paint. Ensuring you keep the body and chassis clean, and well painted will be your best bet.

Those of us who deal with salting have to constantly ensure the vehicle is washed, and I personally clean and paint the frame every fall in preparation for winter.

I use flat black 99 cent cheapo spray cans and coat it on thick after the chassis is all cleaned up. Once a year.

Stay away from rubberizing the frame, bad idea.

A gallon of POR15 and plugging up all frame holes with metal tape will go a long way, and cheaply. Just paint each piece of metal tape when you paint the chassis, you wont even see it.

Eastwood Internal Frame Coating is awesome stuff, works great.

I'm about to use this stuff as well.

I plan to put on a tow hitch, and I want to clean up the frame first. Wire brushes on a drill (also Eastwood), internal coat, and external, too.

I'll probably take pics of the process as I do it, like everything else.

POR15 all the way!

I used POR15 on the frame of my last toy. It was an out of state vehicle that had some bad rust. Normally we don't have this issue in California, so it was new to me. I sanded the rusted areas as much as I could, then applied the POR15 and then spray painted the frame with some cans of Rustoleum. It not only looks clean, but seems the rust hasn't progressed in 2 years.

Take used oil and spray inside of the frame under high pressure, it will prevent rusting for a year . make sure rubber parts stays not sprayed.
Cost- zero.
