A few bits I've picked up in the last week or two
I've already started assembling the models in the smaller box, and the filters are for the spray booth.I'm probably over cautious but as I undercoat with spray cans in the garage, even with the extractor I like to be careful. although to be honest since fitting the extractor the fumes from the spray cans are minimal even in use* but as I can be working with the airbrush for an hour at a go it's not worth the risk (the filters are only about £15 and last 6 months once opened, probably longer as it's particulates not vapours as such most of the time).
*It used to be that after five minutes with a spray can in the garage the air was thick with dust and stank, now even with the mask off it's barely noticeable whilst doing it, and clears completely in about 5 minutes or so (you just get the smell of the paint outgassing as it cures).
