Sanding painted metal

I have some metal shelves where the paint has flaked off, I assume sand/prime/paint would be the solution, but:

1. What grit sandpaper should I use?
2. Can I just use this after sanding and no paint on top?

We use the spray-on galvanise at work and it is good stuff, comes from Sparex in Exeter, not sure if they deal with the public, but worth a try; or come back to me and I will find out on Tuesday how much ours costs.

I'm going to pick it up on the way home from screwfix, if I don't get it done tomorrow I'll probably never do it. What grit sandpaper do you reckon?

40 gt then 180 gt then 1200 gt > primer+ top coats
or
strip with naoh + wallpaper paste> 1200 gt > fancy galvanising stuff
or
wire brush >smoothrite

it depends if you need them to look good or just not go rusty in the shed and if look good what finish you want ( they get easier descending the list)

other options exist, what are they for ?
tahir

They're going to be random junk shelves in the barn

wire brush + smoothrite , let them dry for a couple of weeks to make sure nowt sticks.

or

wire brush and any oil based paint you might have .dry well as above

i have put stuff with rubber feet on paint that had dried as long as it said on the tin and regretted it
tahir

Thanks, will do that. Wipe off rust dust with damp cloth?
Nick

Yes. But make sure you finish the job otherwise live got bare metal with fresh moisture on it.

Guess what happens next?

Guess what happens next?


1. Gets infected with yeast and turns into cider vinegar?

OR (more plausibly)

2. Wife beats me with re-rusted shelves before making me drink the paint?

Replace the shelves with wood, it won't hurt so much, and could also give rise to the yeast and a pint.

Shelves painted and two cattle troughs turned into benches
