I have never used Black Again but am Willing to try it. I use only Prpfessional detailing products with only top qaulity ingrediants. Is Black Again a restorer? or used for general maintenance? Does it inhibit sun fade and the greyish turning process? I would assume that if it lasts for months it must be full of silicones and oils. Which is ok if you use the product consistantly and forever.
