So I just bought my first pump which will eventually be displayed outside my shop under an overhang. While I plan to restore it down the road, I’m planning on clear coating it in the short term.

What should I use? Is any dull or matte finish clear coat ok to use? Eastwood has a Patina Protectant clear, but it’s been out of stock for a few weeks now.

Use whatever you like, but I would use flat or matte. You can also use tung oil. That turns out real good on a pump with rust.

In order for clear coat to adhere, the surface should be sanded and prepped. If not prepped right, it will peel. Sanding and prepping will cause you to lose some of the desired effect.

I have used acetone and BOILED Linseed Oil in the past, with good results. It leaves a semi-gloss sheen. 50% Acetone,50% BOILED Linseed Oil. Do NOT use regular Linseed Oil. It will take a month to dry.
Simply take the Acetone and BOILED Linseed Oil and mix half and half. Wipe on with a rag or brush, let it sit for 20 or 25 minutes,then wipe it lightly with another rag to remove the excess product. Let it dry for 12 to 24 hours, depending on the temp.

This is what I recommend,both in wipe on or spray on.
Boeing developed it to protect metal surfaces on airplanes that have very,very tight tolerances that can't be painted.
I use it on my Galvanized gas tanks on all my Antique cars.
It's incredibly durable and won't harm anything.It's a clear better then wax coating that wears off over a very long time,just re-apply by spraying on a clean rag..

What if any surface prep is necessary for the linseed oil treatment? I noticed your sign has some white, possibly chalky areas that aren’t there after the linseed oil is applied.

Asking because the paint on my pump has quite a bit of white chalkiness in areas, and some rust stains I’d like to remove.

I use this stuff, available at O'Reillys auto parts stores and other places. It doesn't require a catalyst. It won't change the surface colors much at all, usually things pop a little more after clear coating with this and it tends to even out colors some. I just shot some last night actually, dries quickly as well, very easy to use.

You do need a spray gun of some kind to apply. Surface needs to be clean of course. I'm not sure how well it would hold up outside but probably be OK. Can always pick up a $20 gun from harbor freight if you need one, a quart can is about $30.

As far as sanding the surface before clearing, you can. I find it easier to abrade the surface with a scotch-brite pad. Of more importance really is that the surface is clean. I use "wax and grease" remover which is also available at any paint place. There have been times when it's been completely impossible to sand the surface because of the shape, and it's still been fine.

Do not clear or put anything on it. Leave it as is!! There are those of us that do not like this done to pumps or signs. I will not buy a pump or sign that has been cleared.

I just wash it with Dawn. The sign was coated to protect the white from rubbing off. I did not wash it with Dawn, I used a rag with Windex to wipe between the letters, for fear of them rubbing off. When I coated it, I blotted it off with a rag rather than wipe it.

If you want to remove the chalk and rust stain, I reccomend cleaning it with CLR or Purple Power, and a soft brush. You may have to try it a couple times depending on the stubbornness of the stains.

If it is a resale item, I would agree, but if it goes into a personal collection, I say let them enjoy it as they wish. To each their own....

I disassembled these three items in the past, cleaned, and coated in the matte clear I listed above. Most buyers (really all) are happy that they can use or display without worrying about further rust or shedding. The cigarette machine doubles as a liquor cabinet, inside is galvanized shelving.
