Coolant pipe replacement for 987

[Greshamst]

Has anyone had the coolant piping replaced on a 987 boxster or cayman? I got an advisory on my last service that there's coolant crust on the interconnects between the coolant pipes. They're rubber, so on a ten year old car would have started to deteriorate. Looking into it, seems like it's a £700 job at an indy as apparently it's quite fiddly and can take 3-4 hours.

Has anyone had experience of this, or replacing themselves?
