Best anti-rust primer?

Hi all.
Any modern recommendations for a good, easy to apply, effective anti-rust primer? Or are products like 'red lead' still a good/best option? (Is lead still allowed?!)
This will be for applying mainly to already-rusted surfaces, but only light surface rust which will have be brushed/sanded down first. It's important that it can be applied smoothly when needed (ie some uses will involve flat, decorative panels) as well as just slopped on to metals frames and stuff to stop rust in its tracks.
Will be overcoated, so 'primer' function only required. Unless there's a superb all-in-one available? NOT Hammerite and its ilk, tho', as these require their own specific coatings. This will need to be multi-purpose - ie can be overpainted if needed.
Thanks :-)

I’m not an expert in this field but I still use red oxide on bear metal.

Ive recently used Kurust on a rusty bit of a 31 year old Mk 1 MX5 that was causing water to get into the boot then used what was left in the small pot on much of my outdoor metal items such as bird feeder poles, gate and shed hinges and all of my metal garden furniture.
Although its a Hammerite product (which you said you didnt want) , I dont think it needs any supporting products - it just works on its own.
I have no idea on the longevity of the results but each item in the garden/outdoors looks basically brand new after a few hours - specifically though, it also did the trick and im really pleased with the results on the small section of non-structural, metal on the MX5 which I was able to then use a leak sealer product on the body panel joints, prime and then spray. I no longer have a swimming pool in the boot of the Mazda after rain.
I got the Kurust from Amazon

Hope this helps

Like Ant555 I used kurust but on the scabby bits of my transit. On the small bits I just went over with the primer then white touch up pens but on the larger areas I went over with Isopon Zinc 182 primer followed by the colour coat. The Isopon had a nice build up to it taking out minor sanding / pock marks. Sorry might be totally off the mark for your purposes.
Is Red Oxide still a thing but not the good old fashioned leaded type?

Thanks all.Kurust might work, but it would need to form a finish suitable for overcoating - ie be sandable smooth if needed.NSG, now that's an idea - zinc-based primers should do the job! Cheers :-)1

Jeepers any update on what you went for?
I too have a transit with areas that need attention I’m happy to spend the time putting it right but I don’t want it to be temporary!
Got quoted £1000 to have it done professionally with no guarantee, so going to take it on myself.Maybe, just once, someone will call me 'Sir' without adding, 'You're making a scene.'0
