Close up of the K-frame. The right side of the dip line is mostly finished. Left of the dip line the rust pits still had rust in the bottoms and needed more time in the process.

Following electrolysis I wire wheeled the part. Places that couldn't get wire wheeled or hand wire brushed were wet sanded. With a coat of Rust Cure phosphoric acid that was thoroughly wiped off while wet, the K-frame is now ready for paint.

I could have de-rusted the inside of the K-frame if I could have placed a sacrificial graphite anode in there. The anode would need to be wrapped in plastic screen mesh to prevent it from touching the K-frame and causing an electrical short circuit. Instead, I'll just flood the inside as best I can with Rust Cure.
