Quick primer / paint question

[NDT]

Just starting my restoration.
I've got a lot of panels to replace and repair.

I won't be doing the paint myself and it could be a while before the paint gets done (happily the car's in a garage though!).

Any advice on what to paint onto to repaired areas to stop rust getting hold?
I may or not may not get the car stripped before painting - to some extent that's down to whoever paints the car.

Similar situation to me 10 years ago
Most of the car was in paint but there were areas where a new bit of steel had been let in or the paint/rust has been sanded back to clean metal.
I used rattle cans - any that I had lying around.
When I came to paint the car the cellulose primer and top coat wrinkled and cracked. No matter what I did, the crackle finish returned.
Be warned

Zinc primer on any bare metal parts you repair. You can buy it in rattle cans or tins if you have a spray gun.

Leave the paint on the car until you come to paint it then either strip by hand (time consuming as I've done it) or have it media blasted.

If that happens, rub it right down to smooth then spray with 2 coats of 'Bar Coat' which is an isolator. Then prime as normal without flatting back the Bar Coat. Use High Build primer so that you can 'nib back' and then paint with top coat.
