i vote this as its what i wold use but add menzerna first
Yes, menzerna is amazing! :thumbs: I came close to adding it to my post - but you need to be careful with it.
Polishes like Meguiar's have constant sized abrasives in them. ie you can stop polishing at any point.
Menzerna has decaying abrasives, ie they start large and as you work the polish they break down to smaller components. This is the same principle as sanding a piece of furniture with 40 grit, then 80, then 120.
The complications come in that you have to work the polish ALL THE WAY through its life cycle or the large abrasives leave scratches (while cutting) which are not polished away by the smaller (broken down) ones...
You need to understand the various menzerna compounds and how they work with what spec of polishing pad and then test that on an inconspicuos area of paint to see how the combination of pad and polish affect the vehicles particular paint.
So basically, if you are quite confident then go the menzerna route.
Otherwise see what results you get with a Blacklight type product first. - It has had brilliant results with softer paints (such as Lexus) and the Nero Black does require a softer touch, I beileve its quite a brittle paint which can require two componds to correct.
If you wax only - you will just end up with a nice smooth protected finish over your scratches...the dull look is definately created by microscratches not a lack of wax. And these scratches are almost always introduced by incorrect washing technique...
