both, last month I ended up with swollen eyes and in the Urgent care, feeling like someone threw sand in my eyes. Not fun. I now use goggles and a respirator for sanding too. There's only 1 Warning: Causes Eye Irritation. Also they got irritated from sanding right after they got cleared up from the first time
Thanks for your reply - exactly what I wanted to know. Sorry to hear about your experience. Will make sure I have personal protection, avoid the fumes & dust.
