What would be the best car wax brand and type (liquid, spray or paste) for a new black car wax?
If you want a carnauba wax Autoglym High Definition wax gets my vote.
If you want a more reflective shine Jeff's Werkstatt Prime followed by Autoglym HD
Blackfire is kinda in between A carnauba & Werkstatt (Same as Klasse) - good depth and sharp reflections but it isn't a very bright shine.
