Rocker panel minor rust repair

[85Ram50]

I used Skyco Ospho which is phosphoric acid. If you have access to the inside of the sill there are too oblong holes just behind the front of the seat on my gen one, covered with some sort of paper tape at the factory through which you could fill the rocker with treatments. Tortron's idea sounds good.

On treating rust if you are concerned with a permanent repair, you want to clean the area around the rust of paint so that there is at least a half inch of clean bare metal that has had no rust on it, then treat the rust and you have a good probability of getting it all. Once it is cleaned and treated (you can paint directly over the dried Ospho) just paint it as you normally would, a couple coats of good primer, then whatever you are going to put on top. Dupli Color brand is what I am using. For me I use flat black sandable primer. If you want bullet proof use an enamel primer, they also have that under their brand, then whatever color and clear coat you are wanting to use.

I recently sanded and painted the roof of my Dakota, it had a bunch of bondo repairs and rust spots under the factory primer. It was made in Ohio so I figure it got hail damage while sitting in the yard and that was how they repaired it. My Dakota is 25 years old. None of the rust looked active.
