Delaying rust while fabricating.
I sand blasted a 1936 Ford frame to clean and prepared for welding. Then got side tracked by life’s little problems. The frame is inside and covered but is starting to get a little surface rust. I have welding and fabricating to do and don’t want any thing on the frame that would be hard to get off, cause problems with welding or cause dangerous gas when welding. Is there a primer or treatment that would buy me some time? Or would a good standard primer of some sort delay major rust a while?

There are weldable primers available that may suit your needs. You can sometimes find them at your local Industrial paint supply houses, or if not, on the web.
Here is the product from Farwest Paint that we use:
X-6316 Weldable Primer

Being lazy, I just use regular primer with the expectation to sand around areas to be welded as necessary, and to sandblast the thing as a whole once the entire structure is complete (or chemical stripped, that works fine too).
You can buy weldable primer as suggested, but finding it at your local home center is not doable, and it's more expensive. Since I recycle sand, I just deal with having to blast it again once everything is welded together properly.
A friend of mine thought he was clever in spraying his metal work project with oil, and it did prevent rust. But getting the oil off at the end of the project to paint it was a real pain in the ****...
