Armorall is history! used to work on rubber and rubbery and some vinyl products, but I used up the last of mine on the spray-on bed-liner (Rhino-lining) to clean it up before selling the pickup. Used at least 4 partial spray bottles.
In my humble opinion, you can't beat Meguiar's products--cost a little more, but results are consistant! I used various products on my airplanes, and managed to get a leading edge that was too slippery for bugs to attach. Probably gained a whole .5 mph airspeed, but at least the flying machine looked great on the ramp...
