I recently received 3 Vallejo model air paint sets from a friend. He didn’t have the time to build with his second child being born so he gave me his sets so they didn’t go to waste. When I opened the sets I noticed some had what appeared to be rust spots in them. I asked him and he said he had placed small nuts in the bottles to use as agitators. I guess they weren’t stainless steel. I removed the nuts using a telescopic magnet but haven’t tried any of them yet. My question is do you think they’re ruined and I should toss them or are they still usable? I’d appreciate any feedback.
You might try running it though a filter to try to strain the rust out. The rust might just go though the filter though. And no idea what sort of filter to use, sorry.
Just throwing out an idea there.

I had the same thing happen to me. I bought "Stainless Steel" nuts from Menards. I got the rust at the bottom. Removed the nuts...no effect on the color...even the whites. The rust must be very minimal. May be different in your case.

Hello!
Iron oxide was often used as pigment in the old days when there was nothing else. So I guess you should stir the paints throughly and if the resulting colour is OK for you then I'd expect they should be all right. Of course a little experimentation is in order to verify this. Good luck with your paints and have a nice day

I would worry more about the rust grit clogging the airbrush than affecting the paint color. The additional rust affect may work out well.
They make some paint filters for larger spray gun applications. They are paper funnels with a fine mesh tip. IIRC, I have seen them at discount tool shops such as Harbor freight. You should't need the whole funnel, just trim it back to a couple of inches.
Alternatively try something like tea bag material. The coffee pods we use in our keurig has a nice fine filter material included.
Glad to hear that they might be salvageable . I’m going to give them a shot on a scrap model the next time I can get some bench time.
Wow!!!! Perfect timing. I started having the same problem. I bought a bag of SS ball bearings for my Vallejo paint about a year and a half ago. I have been putting 2 bearings in each bottle that I use. Last week I picked up the white bottle and noticed 2 spots of rust in the bottom. Figured I'd just shake it up and see what happened, as there wasn't much left in the bottle. Spots disappeared and when I used the paint in my airbrush, there was no discernable difference. Had no problems with the airbrush clogging either.
I saw a reuseable filter to use any regular coffee in those coffee makers hanging from one of the shelves in the walmart. Was thinking of getting one to see if they work ok with paint.

Iron Oxides are one of the most common pigments used today. Often they are made synthetically, but not always. Iron Oxides are also one of the oldest pigments used by humans.
If you can see the rust granules without a microscope, they will probably clog your airbrush. But there is only one way to find out for sure.
