Good post Motor Fish,
Some ecellent suggestions posted. When handling materials such as sealers,paints, epoxies or whatever, look on the package for the following terms:
Danger-most toxic
Warning-less toxic
Caution-least toxic
Just remember there all toxic.Whenever they say adequate ventilation there has to be some kind of harmful fumes.
Good idea to wear a charcoal respirator when spraying water based paints also. I remember Fishingfreak saying one time your body is made up of water and waterbased stuff can stay with ya.
