Grain trailer painting

[Horn&corn]

Looks like a damp week ahead so thought we might have time to paint the older trailers. Any suggestions on paint type and supplier? How much prep? Red oxide first or straight on with top coat. One trailer not too bad and other quite rusty inside. Just thinking student and a brush but could go for spray if considered worthwhile?
Thanks

Prep is the most important sand back and rust stop

Plenty of it and chase round with a broom.....

Can you use an electric sander on metal? Blow down with air conpressor and whip over with a roller, will give a very nice finish on flat surfaces.

Get it blasted and painted.will cost a bit but it’s job done.

Preparation, preparation and more preparation, red oxide in several coats then a few coats of top coat and don't use it for a few weeks

Surely the paint won't be anything like hard enough.

You can't beat professional shot blasting to prep metal and whatever else they do. I've seen people have it done to metal objects and it comes back delicious looking, I think they dip it in acid as well prior to painting?

in that case pressure washer it ff, dry, and apply paint through pressure washer,
why would you leave it to this time of year to do this, is beyond me

First option is always blast and paint. 2 coats of epoxy 2k primer and 3 coats of 2k polurethane. That’s how we paint our new machinery.

Failing that. Sand back with 80 grit on a da sander. Sake out all rough areas with wire wheel and skim with filler if pitted.
Once all sanded, 2k highbuild primer. Doesn’t matter what brand as it’s a trailer. Once dry, 24hr or so. Sand that back with 240 and then apply 2-3 coats of 2k polyurethane topcoat of what ever colour. If you get stuck on paint drop me a pm. We get ppg paint at silly price as we buy so much of it.

Being a farmer job it may well be a litre tin of some colour,Brunswick green allways seems popular in the agricultural community and a 4 inch brush and done on a wet day when nothing better to do.and want to use it the next day

Clean first with some sort of electric rotary brush and the user wearing goggles and face mask and paint immediately with tractol. Glossy primer red oxide using roller for flat areas and brush for corners

Why bother pressure washing it? Paint over the dirt and the paint will be easier to remove when the job has to be done right.

This was how steel work was painted when I worked at farm building manufacturer in the early 80's and this is how I do it and will carry on doing so

I think the idea is to find something to keep the mind occupied whilst your entire years wages are being hammered into the ground by rain out in the fields....
Don't know why I'm so glum, I've finished my harvest.

Think you slightly missed the point of the question......

Red oxide will dry in a couple of hours, then brush on topcoat, dry enough to use in a day or two

I've recently painted an old spare trailer we matched the body colour with one generous coat of hammerite blue applied with a brush.

But

Preparation is key - good pressure wash first and then remove any rust with a flap disc or knotted wire wheel but wear all the PPE as these can throw bits of wire or rusty metal at the user

In terms of drying time leave it as long as possible

Might be dry in a few hours but will still be very soft and very easily marked

I asked my paint supplier if there was a food safe paint, and the reply was "no"
