Alright detailers, need some help with steamy windows on my 1995 Toyota Rav4. The problem with the car is it has **** ventilation, and no aircon, the windows have been a nightmare during the snowy and wet weather we've been having! Is there anything I can apply to the inside of the windows to reduce or eliminate this? I actually put a coat of RainX on the insides last month to try it out, and whilst it beads away water, it doesn't reduce condensation build up. HELP!
