Stripping a roll bar for painting?

What do you guys reckon? Wire brush or heat gun? Zink primer and satin black finish?

angle grinder with a wire wheel and good eye protection

And body/face protection, had the wires pin me tee shirt to me chest once or twice.

So whats the story with zinc paint? Does it work? Can it be painted over?

I'm after a similar answer, sand down, zinc, etch then paint????

zinc primer is good and paints over well

get it powder coated, Excel in Mildenhall are pretty cheap and do a hard wearing slightly textured finish that they do for a few off road parts companies and Safety Devices roll cages who are on the same estate.

Wire brush on a grinder is old hat, and hard work. Bits of wire stuck in everything in a 10 metre radius like arrows, melts and smudges paint rather than removing it. Try a poly wheel instead. Quicker, safer, quieter. Not great for rust but there's always Fertan.

I used a flap wheel in a grinder when I did mine.

Etch is used on the bare metal (if needed) not on top of paint.
Use etch on surfaces that paint don't like to stick to like aluminium, plastic, galv etc

Cup brush on an angle grinder. Then a zinc rich primer. Then anything except Hammerite.

That old powder coating is good to begin with but rust will soon bubble up under it, I'm not a big fan of powder coating. I did think about galvanizing it.

Fair enough, it's possible to powder coat stuff where it doesn't flake off, excel have al kinds of techniques, especially if you get it hot galvanised sprayed first by a guy in Hockwold that does hot blasting and galv coatings. Things improve........

Could get it blasted then spray it with satin black ceramic exhaust paint I did one a while back came up luvverly and easy to repair if u scratch it..

Shot blast and hot zinc spray, followed by semi-gloss powder coat.

Is that Garner Blast in Hockwold?

Not sure if his name, but he is almost next to the base at Feltwell on the main road, he did some blasting for me a while ago and got sprayed galv
