Put them in cabinets, or in a clean room with filtered air going into the room and supplying positive pressure. I would be interested in other solutions. I will be retiring in a few years, and will be building a house. Kim M

I've got an old cake dish top for after painting. Any kind of a cover you use after you've painted will protect it but try not to use a cardboard box; they shed fibers too easy.

There's lots of plexiglass display cases available on the market for when you're finished. hth

I'd be carefull with the canned air method: the ones they sell here have enough pressure on them to quite literally blow small bits of your kits.

You might also try to use an airbrush loaded with water with a bit of detergent in in, followed by airbrushed water and finally just air to dry the kits. Worked for me on some hard cases; no guarantees though.

It won't be airtight unless you seal it in. You could put a pencil in one corner to pick up the edge just a bit for air transference. Or come back every few hours and pick up the box, inspect your work, keep the fingerprints out of the paint. 8^) That may introduce some dust though so I avoid doing that. hth

I haven't noticed that it takes paint any longer to dry than if I'd let things sit out in the open (I use enamels, BTW). Mind - I don't seal things up, just "shelter" the model under a loose tent of sorts. It still breathes, it's just covered from direct settling of dust from the air.

Usually the box the kit came in is a good size for such, but with some of the big 1/32 jets that I like to do, I end up collecting and saving boxes and/or sheets of cardboard of various sizes - which are also useful for test-shooting at with my airbrush to check the needle setting before spraying the model directly. They're also useful for taping parts, assemblies, and/or sitting whole kits onto to hold for airbrushing. When they get painted up with too much overspray I just throw them away.

I used to have the same problem of dust settling on a freshly painted model and found two techniques to that are quite effective.

1) Filter the paint as you pour it into your airbrush cup. I got a number of commercial paint filters from a paint supply store that I use. They are large paper cones with a filter mesh at the bottom. Looking at one before I actually used it, it looked like the mesh might be too course and not trap anything. But when I looked at the results, there were no particles or clumps on the painted model. These filters are quite large and I cut away most of the paper filter cone with scissors to make it small enough to work with conveniently. These paint filters seem to be free from commercial paint suppliers, at least when I asked about paint filters the guy behind the counter reached down and grabbed a handful and said "here, take 'em". I've also been meaning to try using a needlepoint frame with a nylon stocking filter (I'll ask my wife to buy those).

2) Immediately after painting, put the part in a clear plastic storage box with a lid. This has been remarkably effective in keeping dust of a model while the paint dries. I use a shoebox-sized clear plastic storage box with a hinged lid, although I intend to get a larger one for bigger components. I wipe out the inside of the box before each use with a damp paper towel and place each freshly painted item in the box and immediately close the lid. The parts do not seem to take that much longer to dry and I usually let them sit for 24 hours before opening the box. After 24 hours, for gloss paint, I'll crack open the lid to open it just a bit and let it dry another 24-48 hours. FYI: I live in a low-humidity climate. Oddly, this seems to have virtually eliminated all dust settling on my models while the paint is drying. Martin

I've tried doing an impression of that voice for years and could never hit it. Turns out it's Nancy Cartwright; totally out of my register. Beers,
