This is a couple steps ahead of where I am, but I want to get ahead of potential problems.

I realize dusty environments are bad for varnishing, but are they also bad for fiberglassing? I'm building in a woodshop that doesn't have a system from removing dust from the air, and I see that when I set my phone down flecks of sawdust show up on the screen after I come back to it a few minutes later.

This place is gigantic and used by others, so "just clean up" isn't a viable option. I could glass it elsewhere, but if that's the case I need to start planning now.
