a good silicone for quick gloves in nz and maybe also australia is selleys window and glass.

it's designed to caulk windows in wet areas.

if the glove fits your hand comfortably it should be ok to make a glove with... after you get it wet and play with it for a while it'll loosen up anyway.

try to stay away from cotton gloves as they rot. the best gloves to use are nylon or nylon/polyester blend, (i think), you can get them from photographic supply shops, the developers use them to handle prints etc.
