Rich's process (copied from another thread)...
My process on Black if working by hand.
Wash - lambswool mitt and Chemical Guys Shampoo
Swirl Removal - Megs Scratch X
Polish/paint clean- Autoglym Super Resin Polish
Sealant - Autoglym Extra Gloss Protection.
Wax - P21s Concours look wax, Poorboys Nattys Blue Wax or Pinnacle Souveran depending on your budget.
http://www.seriousperformance.co.uk/ with CS discount will get you the Nattys Blue or P21s, AG from Halfords.
The Poorboys range of polishes are great but better suited to machine use.
