- Wash (fairy liquid)
- Claybar
- Wash (Bodywork Shampoo)
- Super Resin Polish x 3
- HD Wax

Got rid of most of the hairline marks, although I still have a few stubborn water marks which probably need some chemical treatment or orbital polisher to remove. All in all, happy for around 4 hours work though!
