I have followed closely recent comments about the cost of R12 coming down and, in some cases, being less expensive than R 134. The ads on e-bay say that they require a certificate to purchase R12. Since I am interested in keeping my DeLorean "R12", what are the requirements to get a certificate to purchase R12 and how do I go about getting one? Thanks for any information. -rjwilson@xxxxxxxxx To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
