Does anyone know of a good product to use to keep the interior windows from fogging up as I am driving? Now that the cold weather is coming (its here today), my windows keep fogging up as I am driving with the heat on. I have to keep switching from front blower to the defroster then back again...a real pain

I am looking for a product that works well, is easy to apply and a product that lasts, is there such a thing

Thanks for any suggestions,

Scott
