Painting old steel
I was given some old car ramps made of 5mm angled steel. They had been outside in the rain for 25 years and were covered with surface rust so I have
got them both down to bare metal and they are surprisingly good with just the odd patch of the slightest pitting.
I have got an acid etch primer to go on but wondered if I any of those off the shelf kurust type jobbys would be of any use first.

I would say it might make them last longer before the rust breaks through - but it will still break through

They are only ramps, don't get too hung up on prepping them. I would just slap a coat of POR15 or similar on.

Seriously, if they've survived 25 years outside and only have superficial rust then I'd just spray them with WD40 if anything at all!

What about Electrolyses with Lay and then Paint with POR or something. To properly protect them Get a couple of Blocks of Aluminium and attach to the
bare steel . This will work using the sacrificial anode principle - allows oil companies to WET store Christmas trees (under the sea for 20-30
years)..

Not being frivolous, but why try and fight the inevitable? It'll come back through as sure as eggs is eggs. Better to live with it and pick a
paint that doesn't discolour and is a doddle to touch-up year on year.
Our villa's 20 years old and we've steel 'wreckers' on every window (built by a German who was very security conscious).
They're white and tiny brown rust spots show up every two years or so, mainly at the welded joints. A good quality steel paint
'cures' the offending spot indefinitely but it comes through elsewhere. Nevertheless I need only paint around 5% of the exposed area
biennially.

Really???
Just paint it in Hammerite, bloody hell they are only ramps!!!
Mine were rusty when i got them from a boot fair, 2 years and the hammerite is still ok. The bottoms get scratched up quickly anyway.
