1971 duster

One of my latest challenges while building the 67 barracuda is keeping dust off the new paint. I could be making a mistake but I have been using the foamy glass cleaner. Really cool car. There can't be many where you are located?
I got freshly painted non-mopar project car in my garage going back together right now. I just let the dust stay on the new paint until I can get all the glass back in then give it a full wash. Dust on new paint not a good look but I think it you let it be it won't harm anything where as messing with it could scuff/scratch paint.
