What do you put a kit or parts into to dry after spraying?

I use a heated horticultural propagator a bit like this. . .

Silly question possibly

Not at all. . .

The issue of dust is far worse if you're spraying a gloss finish. On tanks and aircraft it's just the first stage in weathering.
As some will know I share my work room with the Mrs who sews and knits and that creates fluff and dust etc so i have to be more careful.
Glad I'm not the only one sharing the space with SWMBO, and for sewing and embroidery. Must admit I've not had a problem with drying on the work bench. But then I'm only doing matt AB so as someone said, dries pretty quickly.

I'm with you - A dedicated paint drying 'thing' would have never occurred to me... Mind you, I do have a propagator standing idle.

You know it makes sense! I'm considering installing a small vacuum device to mine to remove those last dust motes that always seem to settle where they are least welcome!

You wouldn’t solve it, you’d just make it worse. You’d be better off putting a filtered pressure feed on it. Any leaks in the arrangement would then blow outwards and not let dust in. All a vacuum device will do is pull in dust from the surrounding area. Clean room design 101…..work in a filtered air positive pressure environment to keep out contaminants.

Trivia but that reminds me of the debate we always had between US & UK vehicle painters.

As a rule they ran their spray booths under positive pressure, to keep the dust out as you say. In the UK we run negative pressure. Not great as dust always tracks in from somewhere, but it stops the harmful fumes being blown out and reaching the unprotected souls outside!

Brilliant!! didn't think of that, best use the vacuum outlet and not input! It's be warm too!

Weird. I’d think in a professional environment like that you’d just have HEPA filtered clean air inlet and carbon filtered foul air outlets on your HVAC? You could even have clean air laminar flow over the spraying area inside the room if you needed a higher grade of air quality. Both strategies are commonplace in the Biopharma world and have simple design and control so I’m surprised it hasn’t crossed over.
