For me it was entire body tub that had light rust - not flakes, mostly still
metal showing, but rust over the entire surface - from sitting in a garage
for years with no paint after soda blasting. Not counting repairs, prepping
it and priming it was a few days work. Someone mentiond the PPG DPLF primer
and that's what I used. It won't rust with that on it if its indoors. I
also used the Scotchbrite pads and went over the entire surface with the
conditioner (PPG DX579 Metal Cleaner "a multi-purpose phosphoric acid based
cleaner and prepaint conditioner". Then just before priming, I went over it
again with DX520 Metal Conditioner that is also a "phosphoric acid based
coating chemical that will produce a zinc phosphate coating on galvanized or
steel surfaces." Then applied the DPLF primer. The whole process was
probably a total of 16 hours work spread over several days.
I'm sure any body shop could do this as well, as long as you don't mind the
$75/hour. The cleaner/conditioner was around $30/quart and DPLF is very
dear, well over $100/qt with all the components.

Subject: Re: [Shop-talk] How to remove surface rust over entire car?
Howdy,
How much time are we talking about here to do a fairly extensive rollcage
and areas of the car's unibody that have been modified?
Part of why the car is sitting instead of being worked on is that we're up
to our eyeballs in projects these days and have a 1.5 year old that can't
be out in the shop unless someone is holding him.
I was really hoping for some kinda "take it to this kinda place, pay them
$500, and that's what you need" type of deal... Like I can devote a couple
afternoons to this, but not that much more time.
Soda blasting? Is that more like what I want?
Mark
