Good old Screwfix hey ! Have you used Electrox ? for less than half the price this is attractive but the non-porous nature of Electorx sounds like a bonus. Although this is "weather proof". Assume you've had no problems with this and with further paint coats are ok ?
Apologies for old thread revival, But do you still rate SAS zinc primer ? Do you still use it ? Trying to decide to use this or Electrox.
I use a zinc primer called SAS.
I use it as both a primer and a weld through primer and have got good results.
I started using it over a year ago and the metal i sprayed with it at the time is still holding up brilliantly.
As for mig plugging with a weld through primer, i spray the flanges/edges up with it and then clamp the panels up. Where i have the holes drilled for the mig plugs, i remove the primer from the metal within the hole using a wire brush in a drill.
Like this,
It's great stuff and is priced well too. £30 for 6 cans

I haven't used it for a few years now.
At work, I have started using a zinc primer from screwfix of all places!

It's brilliant stuff and only needs a light coat. Plug welds and spot welds thru very well. Only advice is apply it lightly or it goes on too heavily.
I buy it in bulk so save £££
