When I did my car I cleaned back to bare metal and welded the necessary areas in turn. I primed each area as I completed it to keep rust from forming, particularly within the seams. I also used that weldable zinc primer on all lap welded seams. As the whole process was done over an extended period it ended up as a real patchwork of primers, applied at different times, under different conditions (temperature / humidity) and I wasn't very confident of how good the adhesion of the primer was as a basis for finish coats.
I then grit blasted the complete body shell back to bare metal. I borrowed equipment, (windy-pick compressor, grit pot blaster, moon suit and air-fed helmet) and had a very, very dirty 3 hours!
When completed I was amazed at just how clean and bright the properly clean steel really was. The car looked like it was silver plated!
I then immediately blew all the surplus grit out of box sections and crevices and gave the whole thing a going over with spray applied acid etch primer. This needs to be done as soon as possible as the very clean metal will begin to form micro-rust very quickly if there is any moisture in the air at all In my case it was all etched primed within 30 minutes of being cleaned.
I then lifted it back onto the wagon and took it back home where I applied the first coats of normal base primer. It was a busy day and very hard work on my own, but by the evening the visual change to the car's appearance all in one day was one of the high points in the whole rebuilding process! After months of patching and fitting panels it was suddenly transformed in a single day!
