I have a similar question.
I plan on putting a coat of Blackfire Wet Diamond with Polycharger on my space gray E92.
I should note the car has clearbra on the front end and fenders.
the car was delivered in august and lives in my garage, I see no major issues with the finish that need correcting.
i was planning on washing, then just applying the Blackfire Wet Diamond. Is there a step i should do before applying the blackfire? considering i have no current finish issues and the clearbra.
