RE: RainX is great
Awesome - I had no idea they made a version for inside the car. I also agree that it's a cool visual effect to watch the water beads dance around. Especially on the flat window of a Jeep Wrangler. With Rain-X, I don't even need my windshield wipers.
It was particularly annoying because I have a 4 cylinder and every time I turned the defroster on, the engine's power was greatly reduced (it is designed to automatically turn on the A/C to dry the air with the compressor).
Although your vehicle is different, you can get around that if you're comfortable taking your dashboard apart and soldering. One of the wires leads to the A/C relay and is activated by either choosing A/C or defrost. If you splice a switch inline with that wire, you can have A/C-less defrost or A/C defrost just by flicking the switch. It's a handy feature on a Jeep because the only way you can get top/bottom air simultaneously is with the A/C selected which is pointless in winter. Having the A/C override switch lets you use the vents however you want in a Wrangler. But it would address giving you more control of your defrost in your S10.
