I have a project I am working on, and I plan to spray paint the shell of a loco. But, I have a problem. I recently painted a scrap piece of plastic to test the paint color. When I did this, I noticed that there were many little dust particles stuck to the paint as it was drying. If it weren’t for the dust particles, the coat of paint would have looked pretty good. The question: Is there any way to paint it without getting dust or dirt on the drying paint? When I painted the piece, I did it outdoors, and them moved it indoors to dry. It is particularly dusty indoors, but if I leave it to dry outdoors, the wind will blow little dirt particles onto the paint. Any suggestions?
