I once built a sailing canoe on Majuro Atoll, Republic of the Marshall Islands. I used Pandanus keys washed up on the beach as paintbrushes. Pandanus is a local fruit. After it's been bashed on shore for awhile the fibers at one end make a nice brush. I didn't have rubber gloves to use with the epoxy. So I figured out this nifty way to put a plastic disposable shopping bag on like a mitten and use it instead of a rubber glove.
I've been using this method ever since.
