Hi
Before primer I am washing the plastic with warm water and a little liquid soap But when I spray the primer, I still find some lint here and there, How can I totally eliminate lint?
Regards Andrew
I usually give the subject a blow down with my airbrush at max PSI before laying down paint. If you dont have an airbrush, you could give the subject a brush over with a wide, clean brush, or possibly use an lint free anti-static cloth.
I read spraying the air in the room with water mist 10 minutes before painting will help drop the dust out of the air. Of course maintaining a clean work area is important, if vacuuming do so a hour or two before as the exhaust from the vacuum stirs up dust also.
Also, if you don’t have an airbrush, try a hair dryer. Just don’t get too close to the model.
Also, are you wiping down the model after washing it or just letting it air dry? I just let my models air dry after washing.

Yes let the paint cure on its own time. Acrylics take 1/2 to 1 hour. Enamels take a few hours to 12 hours. All depends on the humidity in the room, temperature, amount of thinner used and the thickness of the layer. Flats dry quicker than gloss coats. Future acrylic clear gloss takes 24 hours to fully cure.
One suggestion is to cover the model when drying. I like to use clean plastic containers to keep dust & contaminants off.
I do have an airbrush.
I will try to make a spray booth or buy one
Even a spray booth will not completely eliminate dust. Turns out spraying, whether from a rattle can or airbrush, can put a charge on part being sprayed in dry weather. Sort of like a less-efficient electro-coating. The suggestion to spray water in the area before hand is a common trick. I find the spray booth does drag dust from area into the booth, and anything that lessens dust in area is good.
I get the freshly sprayed part under a box as soon as possible after painting, with the box propped up for air exchange. I am intending to make a permanent version with filtered air inlet and outlet. Some friends use food dryers, but I am afraid of those running too hot (they do not have good temp controls). So my gadget is not to speed drying, but to keep part/model in dust-free environment while it drys.
Point of spray booths is to keep paint overspray from shop. I remember the “laminar flow benches” when I was working, where air was drawn in, filtered, and blow through bench out towards front. Something like that would be ideal for dust elimination on model, but would make a mess of my shop
