How do these guys prevent dust in their paint jobs? :(

[corvettekid_7684]

Get a "tack cloth" and gently wipe the body down before painting and between coats also. I paint mine in a dirty basement but I dont have too many problems with dust in my paint jobs. More the occasional cat hair drifting in, (I have 3 cats) but if I catch it, I stop spraying til its dry and take care of it. Usually a swipe with the tack cloth will be enough to pick up any dust or cat hairs that do make it onto the surface while painting

PS My paint jobs are far from perfect, but its not due to dust

I always ground/earth bodies to help eliminate static,I use a wire coat hanger to mount the body then run a wire to ground from the hanger.
Tack rags can be used carefully between coats but use a light touch.

Those videos are pretty low-res and you only get a glimpse at the close-up finish a couple times.

Take a look at the first video around 5:55 - 6:00 and again around 6:50 and at least to me it looks like they have lots of dust and even some orange peel showing when the light reflects in the paint.
