I've generally done sanding of fibreglass outside because it's messy however the current weather makes working outside inpractical so I'd like to do it in the workshop.  The problem is when I sand in the workshop the dust goes everywhere and gets all over everything.  While I ware a respirator while I am actually sanding, I don't use one all the time I am in the workshop so I could be kicking up dust which has settled on things and then breathing it in and I know it ain't good for me.  So I was thinking if it would be possible to construct somekind of tent in the workshop to contain the sanding dust.  Either a ready made tent or a self made one.  I was wondering if clear plastic sheeting or maybe tyvek roof membrane would be good matirials to use if I was to make my own tent.  Has anyone ever tried making anything like this?
