Swapping the tub on my Jeep and while I have it off it's time to clean up and paint my frame. The frame is solid but there is a good amount off surface rust. Currently I am using a needle scaler to remove any loose or flaking rust. Every thing that is left is solid but still rusty. Looking for opinions on what products to use. Rust conversion vs. rust encapsulation? Type of primer / paint? I was thinking using an oil based paint for the top coat. Needs to be something I can tint locally as I want to use a wild color for some parts. Valspare makes an oil based rust exhibiting paint I can tint at Lowe's. Any help would be appreciated.
