I would go with CG Glossworkz. If your paint is in good condition it is a good product levels itself out. easy on easy off and good results. A little pricey but it lives up to the hype.
Poor Boys black hole has cleaners in it. Now whether it's a abrasive or chemical I am not certain. Now for the formulated for darker colors. Poor boys pulls off Houdini's with being able to use products in direct sun with pro results but the whole formulated for specific colors is a gimmick. The base of the fillers is Montan wax which derived from coal and is dark brown and black in color. It is also used in Nuba waxes in bleached form to soften nuba to make it easier to spread.
You can put Black Hole on a silver care or a black car buff it off and the silver will still be silver.
My pic goes to Glossworkz for easy on and off, no caking, self leveling and no dusting from the fillers.
