This goes double if you are using automotive 2k clear. You need a full face respirator with carbon filters. A half mask is fine for base, but for clear , the nasties in the hardener can be absorbed through the eyes. Wet sanding can be done after a couple of days, but to fully cure without the aid of baking takes 8 weeks.
