I have been hearing alot of good things lately but the best i have heard so far is that FREON MAY BE BACK IN A COUPLE OF YEARS!!! is anyone as excited about this as I am? My dad used the last one on his cadillac well so he thought (hehehehehe) I had one hid way up on the top shelf and put it in my jimmy a few years back and I am telling you it makes you want to drive the thing for every small errand because of the cold air despite the fact it is a total gas hog.
