So i picked up a pretty clean vert shell for $800. Has the normal rust bubble near the windshield. Qustion what are you guys using who had this problem to neautralize the rust. Ill be using a galvanize spray but just seeing what else is put that works best. I already starte . To tackle this project. Surprisingly enough this is the only spot that has rust.

I've always used a rust converter, but never had anything that big.

I had very similar rust. I used POR 15, but since then I see many comments that Rust-Oleum spray will do just as well.
