Corrosion control - inside roof / headliner area

Since most of the headliner material has been removed, I can see that I need to deal with surface rust on the inside of the roof.

I purchased two cans of Rustoleum Rust Reformer.  Its supposed to convert the rust and provide a primer surface for painting...

Tomorrow I plan on taping/covering the inside of the car and spray a couple of coats of the rust reformer.

I am also going to remove the back seat and package tray, so there will be no concerns of overspray on those pieces.

Hopefully this works as advertised...
