Finally got round to sorting this out today.
Full wash with megs, dried then time to treat with the Farecla
Before
After
After SRP and wax
Wow what a result, thanks again to everyone for your recommendations especially Dave (wu56shooz or something lol) I think your name was Dave ?
Lessons learnt:
Need to repeat farecla a few times and don't be stingy with the quantity
Use a lot of force and different motions
Use a microfibre to apply easier to apply force
Cheers
