Is lining the tank a DIY thing( looks quite simple on the POR 15 video on YouTube) or are there any specialists who will take the pain ( and mess) out of the process?

There are specialist who will take the pain out of the process, but they replace it with a pain in the wallet...
I used Hartlepool Radiators and their Re-nu process. Basically they open the tank up, blast it inside and out, weld it back up again and then bake their own proprietary coating onto it. They offer a lifetime guarantee, but it will set you back the far side of £300 depending on condition. I'm sure there are other people out there doing different processes and possibly cheaper, but this seemed a 'do once and forget about it' deal, which appealed.
