Snow and wipers are like oil and water. they dont mix

[KONG]

This is the second time that snow has fallen while owning my hummer. The first time, I was driving on the interstate and I wasnt to pleased with the way the snow just packed on the windshield and the wipers werent very effective so I replaced them with new ones. Now for this last snow fall, I got totally upset with the build up again on the windshield. And after a while of driving, the wipers froze and were useless. I had to stop and wipe the snow off the windshield and clean the wipers only to have it happen again 15-20 minutes later...
What have you guys done to your H2 to prevent this Build up and wiper failure?
