Ok, as I prepare the shell and do bits of welding Im cure rusting the area then giving it a quick blast of zinc primer to protect it before painting.
The underneath, under arches, bulkhead and interior floor etc will be hammerited.
Will the hammerite give a good bond onto primer?
The inside floor has been hammerited in the past but once you get an edge up it just comes off in sheets so it didnt bond well at all.

The latest iteration of Hammerite is to put it bluntly crap!!

 

Rust-Oleum seems to be far better although not something i would use on a car but thats a personal choice.

Generally speaking Hamerite gets a bad reputation and this is not without cause. Poor adhesion to the substrate, pin holing, takes for ever to cure and overcoating is a nightmare.  In saying that if you can apply it with a trowel, get it thick enough in one application and give it time to cure it will give good service but brushing/spraying on I have never found to be good.

I once heard a South African radio program about metal protection.  It might have on President Reagan's "watch" when he had the Statue of Liberty painted with Hammerite.

 

The paint was thinned, and starting at first light, spraying started. After a couple of hours the area was resprayed a slightly different colour, and this was repeated half a dozen times throughout the day, and the next day they moved on to another area, and so on.

 

It was postulated that it was "job-done" for 100 years.

Is the hammerite still "on"?

If you're not worried about how the area looks and only want something for rust prevention, then I personally swear by Dinitrol products.

Save it for brackets and the like.
The hammer finish is as a result of silicon in the product and therefore cannot be overcoated with any other products.

I got the smooth stuff in white and to be fair when ive used smooth stuff before on railings and the like the finish was quite good.
Cant see me having any other use for white though.
