On mine I used the Farecla G3 range.
I used, the scratch remover (green sticker) and the paint rejuvenation polish (yellow sticker).
After that, I used chemical guys glaze, followed by meguiers carnauba wax to seal it all in.
Halfrauds had a 3 for 2 on cleaning products at the time, I bought everything from there apart from the glaze.
