I just painted my 55 frame with Acrylic Enamel in the garage booth (blue tarp all around)with a 20" filtered fan blowing in and one blowing out.

After spraying and letting it dry I observed some dust particles on the frame.

I want to paint my cab and fenders soon using a 2 stage paint.

Is there a way to eliminate these particles?
I was thinking of buying one of those dust filters from Harbor Frieght if that will help.
