down to a low luster (on the dash) and its perfect, and the back-to-black and forever black (contain black "dye") did not work anywhere as well as this Meguires, like I said I've used the ones you speak of and the Meguires has so far worked the best because if you apply, then let set for 10 minutes then buff to the gloss you want, then let fully dry, it leaves the desired shine level and hardenes to a dry coating that is great. 2 days later I am very impressed, the discoloration/water spots on the old bumper rubber does not show thru as with Back to Black/Forever black. As someone who details at least once a week (yes really) I have tried so many car-care products and am very happy to date. Lets see how long it lasts, passed its first washing w/o loss of shine!
