We've had an insane summer for all us jeep owners in illinois, but now we're in september its time to think about colder weather. This will be my first winter with the TJ and I'd like all your advice about keeping it in good condition - as I'm sure anyone knows, Illinois loves to throw down the salt and I'm told its kryptonite for Jeeps;
so (a) should I undercoat/protect the underside somehow .... I'm not mechanically inclined, is there a place that would do it and what do I ask?
(b) do I anally powerwash the underside of the jeep if I've been out in the salt, or just best to avoid the salt and (urgh!) use the "minivan"
any other tips for me?
