Would you rather see a cleaner-polish/ sealant so that it can be used underneath BFWD to pre the paint or would you rather see see a cleaner-polish/sealant/wax that brings the full 'Wet Ice over Fire' look (although to a lesser degree obviously) in one step?
I would love to see a Blackfire version of Jeff's Werkstatt Prime Strong. Something with strong cleaners a small amount of abrasive polishers and a little of the Blackfire shine. This could be step one All Finish Paint Protection could be step 2 and Wet Diamond could be step 3 with Deep Gloss Spray as an in-between-washes touch-up.
