I live in an extremely brutal winter climate. If anyone here has been to Ottawa in January you know what I mean. -40 celcius temps, with lots of snow, which means salt, more salt than you can shake a stick at. Salt everywhere, on your clothes on your body, and on your dog. I have been told that I should undercoat and undercoat now, yet I dont know how much faith I have in the person who told me. So, for all you experienced RAV experts, would you recomend an undercoating? Any other advice for brutally cold climate would help as well.
