I just regassed my wife's Honda **** at the weekend using a kit from Halfrauds. £25 for the gauge and hose and £15 for a can of R134a with oil, cleaner and leak seal premixed. Icy cold again now and holding pressure.
Found this kit on ebay for R12 to R134a conversion - no idea if it has the right connector for a 32 though.
