Good stuff. Do you have or do you know many people who use some sort of color blender, example DBC/DBU 500 or other brands equal? What do you think this would do for adhesion? I only ask because the question asked was about factory sanded clear as would be needed for a blend on a repair whether it be blend within panel or blend panel.
Like you said fresh paint would have better adhesion, so would the grit matter as much on a flow coat type situtation? I like to use 600 grit on a flow coat but have done the same over 2000 grit. As far as adhesion is there a difference in this case?
