Thanks, Don and Phil
I'll be using only the various metal finishes, followed by one of their clears, depending on the bright or dull finish desired for the individual jobs. I have read that once dried it's a very durable finish, so I'm thinking a very light sanding with super fine grit pad, inside a properly masked area, should permit minor dust to be taken care of.
I do use a home made spray booth with filter, strong explosion proof fan, it moves a lot of air so hopefully that will keep down any dust, I don't experience much if any, using regular acrylics or enamels. Thanks again, fella's.
