NE Rust Project: Any more suggestions?

Greetings. My 06 has far more rust issues than I previously thought, so my fall project is to wire wheel and paint the frame with the Rustoleum Rust Reformer. I have collected the implements of destruction and I am now nervously waiting for the right time to do it.

I was basically going to follow this procedure:

Are there any suggestions on how much of the Tac should be disassembled or taped?

How bad would it be if everything gets painted black?

Alternatively, does anyone have experience using Loctite Extend Rust Treatment? A coworker in TN used it on his bushhog and it has long stopped the rust (though salt is not an issue for him).

Thanks
