Freeze 12 Recommended to Me - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Talked to a guy in the neighborhood who's been in the car repair business all his life (mid 50's guy). Said that they recommend Freeze 12 when changing over from R12. I may go with that in light of 134a not being designed for the 77 A/C system. 134a will work, but the A/C tubes need to be smaller diameter to work great. I know this has been hammered on this forum and I did some searches on it. But, has anyone done any conversions lately and what were the results? I'd do a conversion myself, but someone said that Freeze 12 requires a license too. Correct? Also, anyone got any ideas on leak finding? Something for the pro?
