Sandblasted Bunk Bed. Drool. Rust. How to Protect?

[keith204]

I sandblasted a floating bunk bed, and we recently realized the issue of wetness that causes rust. Doh.

I'd like to apply something - some oil, or something that can help prevent this. Ideally, something that won't rub off on the sheets. And I'd like to apply it in place....

I'm figuring this solution is unlikely. But, is there something I can apply to this so that it will at least somewhat resist rust?

Don't say paint.

So you want the bare steel?

Powder coat.

As stated above clear coat will help but you will still get some rust.

Phosphoric acid will form a layer that will resist rust. Still won't last long in a humid environment.

You do present a challenge. Paint is the obvious answer. Anything oil based will be wet and rub off on sheets. Leaving it in place rules out having it powder coated or plated.
I don't know of any wax-based finishes. Chemical treatment is about the only thing left.

A good wax coating will help. Doing a full clear coat paint will keep it at bay pretty good, but you will still see some rust creep in overtime. Bare metal takes a lot of maintenance to keep it bare.

Heat metal and apply Bees wax.

My daughters have a gymnastics bar that has a bare metal component and it rusts from being touched (salt in hand sweat). I wouldn't even consider trying to keep a bunk bed rust free with kids climbing all over it. I know with our race cars we would keep the chassis raw and Scotchbrite/WD40 them, but that was a non-stop chore.

I made a 'holder' (can't think of a better word) for upside cakes to cool out of steel scraps in the shop. Most people use a wine bottle, but we don't drink wine. I sand blasted the holder, slathered it in vegetable oil, and stuck it in the oven to cook the oil in. Has sat in the cupboard for years and has not rusted.

I'm thinking a propane torch and a rag soaked in vegetable oil could net you similar results. Warm the steel (evenly-ish) with the torch and then rub the vegetable oil into the metal. Let that soak in for a while, then rub it down real good with clean rags until the rag comes back clean and dry. Whatever you use, make sure it's safe for the rug rats to eat.
