Doug,

Remember that urethane finishes use extremely toxic catalysts to harden them. These catalysts are cyanide based, so painting with them without using a supplied-air breathing apparatus is risky. Urethanes are severe sensitizers and should not be used without certain precautions, such as supplied air and skin protection.

Fish on.........
