How bad is it to breath epoxy fumes? I was reading through the safety section that came with the material and it said nothing about using a respirator. I was under the impression that it was a must. The safety section warned against getting epoxy on skin or in eyes, suggesteed skin and eye protection, but made no mention of breathing protection. I plan to use my oganic respirator, but I was curious as to why no mention of this was made in the material. I lost way to many brain cells as a teen-ager and want to keep what little I have left.
