Painting raw steel w/surface rust?

[MyOriginal66]

I have a seat frame made from bare steel tubing. It has minor surface rust from sitting around. Do I need to blast/sand it or can I use rustoleum primer and paint on it as is?

I would just lightly sand the surface rust off then prime and paint.

wash down with solvent then wipe on this stuff. http://www.homedepot.com/buy/klean-strip-1-gallon-phosphoric-prep-and-etch-gkpa30220.html
then rinse and prime then paint,
I use the klean strip with a kitchen sponge with the green abrasive pad on the back. just scrub it on let it work with out drying out then scrub again and rinse with water. Dry and prime.

1 part vinegar 4 parts water will do the same as that stuff will.

If you're going to paint it black, you can use Chassis Saver and paint right over the rust (like POR15, but no prep or other steps necessary).

POR15 is incredible stuff but hard to get off later.
