Years ago I sold Dupont Paints. We had several customers that used Imron. Everything said above is correct. Imron was used primarily for Aircraft and Industrial applications. We had one customer that used it and came in one day saying, "Man that Imron is nice stuff but it makes me sick!" We found out that he wasn't painting with a fresh air suit. We sold his employer (We actually made him buy it or face a law suit) a fresh air suit the next week. If your friend recomended it he is probably aware of the side affects but make sure just to be on the safe side.
