Regarding A/C sealant, there is such a thing for the R134 variety. I don't know if it's compatible with R12, but it does indeed exist. I tried it in my '97 Jeep that had a leak so small the dealer couldn't find it, suggesting to me that I just "add a can" once a season. I found the sealant at the local Pep Boys, put it in my near empty system with a "universal" hose, and it has kept the A/C cool and working for over a year now. I forget the brand name, but it's a normal stock item here in Southern Calif. Scott DeForge '62 Imperial. __________________________________________________ Do You Yahoo!? Yahoo!
