The Accumulators are bad for rotting out on them but 50-60 quid normally fixes that.
Get yourself a set of the release clips for the pipes off Ebay there cheap and useful if your going to be messing about with the A/C
I've gassed my A/C about twice in the last 6 yrs and it's ice cold.
Stay well away from those stop leak potions as it gums up the system.
It's a great thing at this time of year.
What I will say is the wholesale price of the gas has recently rocketed recently so if anywhere is offering it for under 75-80 quid a re-gas grab the opportunity quick.
