This is more wisdom from Gary Hunter, well worth taking on board. Next time
at Sun & Fun find him on the Exxon stand, "Flying Tiger" Bruce Bohannons
new beast, and say thanks. He's a nice guy.

too. (imho, of course)
>Yes, Butyl rubber gloves are resistant to a very broad range of

>In the resins laboratory here at Shell Chemical, we use disposable

>Personally, I buy mine from Harbor Freight - about $10 / 100 (10 cents
>each). They are thin, the quality (tear resistance) varies from lot to
>lot. For short little lay-ups, I wear one pair. On longer lay-ups, I
>will double up and put on two pair. That way, when the outer pair
>becomes really gunked up with resin or gets tear in it, peel it off and
>a new pair slides onto the dry inner glove without grief. Get it ?
>It works for me. The fact they are so cheap, allows me to use them
>without hesitation. It is amazing how our frugality will sacrifice
>personal safety. So to combat that bit of human nature, I buy the
>cheaper gloves and use them frivolously without guilt. Some people have
>posted that they wear a separate thin cotton liner glove. The cotton
>liner helps to keep your hands from going "pruney" from sweat and helps
>facilitate glove changes too. I can see how that will work too. Check
>the archives for sources on the cotton liner gloves.

>The down side of the disposable butyl gloves is that they do not provide
>much protection for you wrists and fore arms. For that I choose to use
>barrier cremes on the areas of my arms. Recently, I noticed that one
>of the major laboratory supply glove manufacturers is offering a
>disposable nitrile glove with a longer cuff to provide better protection
>of the wrist and fore arm areas. Good deal.
>
>It is matter of personal choice as to what form of protection you use.
>But, I highly recommend you wear some sort of protection.
