I hadn't used gloves until my first comp last year, and I found that I like prepping bbq with them. It keeps the rub from caking up on my hands. I use insulated rubber gloves for taking food off the cooker that have been washed and cloroxed and washed again, then nitrile gloves for anything else.
When I prep, I don't change them all the time.. I wash when needed and change between meats.
