My friend's Ferrari 488... Black.... It had many details. They wiped stuff on the paint, but they never really cleaned the paint - they kept putting layers of quick detail crap on it
. I researched a solution....
Meguire's Wash Plus. You wash the paint, but use an agressive motion like you are polishing it. The soap is a fine- slightly abrasive soap. You want to REMOVE all the old waxes & contaminants. Rinse as usual.
Then you are ready, on a very clean - paint surface.
After I did the wash, I could see what condition the actual paint was in.
( Here's the bonnet (hood) on the Ferrari)... Notice the raw paint condition on left, 1/3 side of 'hood' in photo, and new Carnuba wax on center -to- right side. It came out like a mirror.
Waxing was easy.
