I cant upload a video.
Let me try again.
Basically, after the usual washing and claying and drying.
I got out the paint meter to ascertain the paint depth is ok to work on it.
I sanded it using 1500 grit, basically removing around 5microns of paint.
Then i polished it using my milwaukee rotary and a compounding pad - Sonus - with Menzerna intensive polish.
Then i hit it with my favourite polising/finishing pad - Meguairs middle pad(yellow) with Menzerna Final Finish (not the ultra fine but the grey polish).
Job done.
15-30 minutes work.
