Well I couldn't cope with the state of the wheels, did a bit of research and popped to a local'ish company today, decided on the colour finish, loan wheels on.
They are not just getting sanded and painted but, tyres off, fully stripped, either dipped or bead blasted, checked and repaired if need be. Base coat / powder coat then finish and clear coat.
Tyres then re-fitted with new valves and balanced.
