Guys, How bout using a thermostat controlled heater that you would use in a incubator. I remember as a kid we had a box that we would put duck eggs in to keep them warm untill they hatched.
Guys , I go in the kitchen and steal some tinfoil ,use the factory edges on the bait side of the bill and wad the rest up on the bill to protect it from over spray when finished peel/tear it off and throw it in the trash and you are done.
