I'm just thinking probublly sanding in the work shop with out any ventilation, you know! You can never get the glass to ay flat. You allways have to sand the rough edges off!
Oops tony you scared me there. I have been kind of breathing g10 which I think is fibre glass to right? I have been sanding and cutting g10 frame to get the vibe frame fixed in my apartment. Oops.. It's not the fibre glass powder but is g10..
Again. Oops!!
