I used poly for about 4 months, most of the time without using a charcoal respirator ( dumb ). I never got sick feeling, but lightheaded many many times. evacuate yourself to fresh air when you are not needing to work directly with the resins. No sense in hanging around watching resin cure.
I’m going to purchase a new charcoal respirator ( my paint store has them on sale for $14!) while working with any epoxy. I have to admit 98% of the time i do not use respirator with epoxy. Dumb again… I shouldn’t take health risks like this.
I have used acetone for many years 10. I feel i did get some adverse nerve effects from coming in contact or breathing the fumes even though I use small amounts but I do use it every day. Again… buy a pair of chemical resistant gloves and wear a charcoal respirator.
