Note: keep in mind that using this paint outside does not mean that now you are free to paint the outside areas. However, you need to repaint the walls and surfaces each year or after realizing the need for a repaint. Some people are curious about how long interior paint lasts; it depends upon paint type and the surface.
How long will acrylic paint hold up outside?
I’ve never painted on steel but I won’t let that stop me from giving an opinion.
If you gesso the pan – once it dries you have essential encased it with plastic – Acrylic paints are water based, but after 10 minutes or so the water has evaporated leaving a layer of plastic. I have had iron pans rust, but never a steel pan that I’ve kept in the kitchen. In fact I can’t recall anything made of steel that has ever rusted when kept inside my house.

You may want to be sure it is steel and not galvanize, different primers.

Water-based paint + steel = rust. At least two coats of an oil-based primer/sealer, probably Rustoleum. The steel also needs to be clean. Google ‘prepare steel for painting’ for instructions.
Depends how he cover.. more important than with what he covers is how completely he covers it. Oxygen rust things not water (Water just put the dust that protects the surface in suspension allowing oxigen to reach it) So whatever covering way you use, do it PERFECTLY.

Thanks. Can you apply the acrylic paint over an oil based primer? I will do some google searches.
I wouldn’t. You can paint oils on top of acrylics, but not the other way around. And that is what an oil primer is. The paint will just be like a glove on top, very easy to peel off.

[*]Using medium or fine grit abrasive paper remove everything that isn’t steel – take it down to bare steel.
[*]Wipe away any dust with a weak solvent – one that evaporates quickly. For small projects rubbing alcohol works great.

You guys seem to be forgetting that this isn’t a car and it isn’t a ship, it’s a decorative piece of steel that will be kept indoors. I work in an industry where our equipment is exposed to the outdoors (and sometimes nasty chemicals) and used in water processes and I have been involved in specifying coating systems for it. I would never suggest that an artist would need to sandblast, wipe down with a nasty solvent, prime with epoxy primer, apply an epoxy intermediate coat and then a urethane final coat but that’s what I expect of the equipment I design every day, a piece of decorative art does not need to meet nearly the same requirements. Bottom line, all you really need to do is clean the steel, seal it, and prime it and it won’t rust on you. You can even do this with rusty steel, seal that rust and it will rust no more as long as you have good adhesion for your sealer, (removing oils is a must.) How many paintings on old saw blades have you seen? Many of those artists just coat the blade with a clear sealer and paint right on top of that and they hold up fine, some of them are even displayed outdoors.

That is why I said the important part is isolate from air (the seal), since its oxygen that causes any oxidation. A piece in steel will likely survive far longer than on anything else saved someday someone find a way to paint in a plate of diamond 😛

If it’s unopened, it’s probably still usable.
Unopened cans of paint last for years when stored correctly. Unused latex and water-based acrylic paints last up to 10 years, and the shelf life of alkyd and oil-based can be as long as 15 years. Since unopened paint hasn’t spent much time exposed to air, it still has the same ratio of liquids and semi-solids, although the ingredients have probably separated over time. But if you stored the can in the garage or shed where it froze or was exposed to extreme heat, even fully sealed contents could be ruined.
Pry open the can and blend the contents thoroughly with a paint stirrer. This can take five minutes or more, so don’t rush it. Dip a brush in the paint and brush it onto a piece of cardboard. If the paint goes on smooth, you’re in luck! Go ahead and roll that wall. If it contains grainy lumps that you can’t stir out, exposure to extreme temperatures have probably changed the paint’s chemical makeup beyond salvaging.
Even if it’s opened, there’s still hope.
Because opened cans of paint are exposed to air, they often develop a thickened skin on the top that should be removed with a paint stick before attempting to stir the paint left in the can. If the remaining paint blends smoothly, it’s good to use in your next paint job.
Like unopened cans of paint, opened cans can also suffer from exposure to temperature extremes. The difference? Lumps in a partially used can don’t always mean that the paint is unusable. A few in a gallon that’s otherwise smooth may indicae that some of the thickened skin on the paint was stirred into the good paint underneath. Before using the paint, pour it through a paint strainer (available at paint stores, home centers, and online vendors like Amazon) to remove the lumps and proceed as planned.
Take a whiff.
A foul or rancid smell, or the presence of mold in the can, means bacteria has contaminated the paint—it’s time to throw it away. Dispose of spoiled paint in accordance with your local toxic waste disposal ordinances.
Paint is expensive, and it can be tough to match custom colors years later. Whether you want to save a partial can of paint for touchups or you ordered too much and have a few untouched gallons on your hands, you’ll get the best shelf life possible if you store paint indoors, preferably away from extreme temperatures and sunlight. To store a half-empty can and make the paint last, place a piece of plastic wrap over the top and then use a tap the lid back into place with a hammer. While you’re at it, mark the date and color name in marker on the side for easy future reference.
