I recommend using Picklex 20 or
Purple Power De-Ruster Metal Conditioner/Rust Preventer

treat any bare metal while working on the car,it makes welding so much nicer with alot less spatter ,apply it over welds and later when you're ready for bodywork, just roughen it up and go. I've been using it for a while and love it, you can pick up Purple Power De-Ruster at Advance Auto Parts for around $6 a bottle, Picklex is alot more expensive
