Intersting how the tone of this thread has changed, I'm glad to see it. We often take the little safety matters for granted.

I do know the thickster gloves are Latex but they are a much thicker latex and seem to hold up much better, but I also keep nitrile gloves on hand in the shop, maybe I need to adjust my technique some.

Chuck,
I'm glad you cleared up the cumulative affect of the Isocynates but it is not the sensitization a cumulative affect? The more that you are exposed to the chemical the more likely you are to become sensitized to it?
