what do you use to block cold air from Radiator

I use a chunk of cardboard sprayed with some rubberized undercoating. Holds up well to water, just had a few days of rain (now snow) and it doesn't fall apart. Cut to leave about 2 inches of radiator on either side. I also take off the fan during the winter, warms up enough to move the needle with the idle bumped up to 1200 in about 5 min, and with the plow on in will run right around 190 on the highway, 170-180 around town.
