Just came across this thread and realise this is where the expert offer 'informed' advice.

My car's ok... recently compound + polish + wax.

1. The problem is the glass, windows, windscreen etc. All have heavy swirl marks, any particular product recommended to cut/polish back the glass? My glass is JDM and comes with 15% natural tint.

2. Water marks all over my side mirrors. A detailing shop told me that it's dangerous to use off-the-shelves product on side mirror as some might 'darkened' as a result?
