hi everyone..i read this post a few weeks ago but cant find it...i have rainbowing and spotting on the exterior black trim arond the windows and someone said use maguires scratch x and then someone posted a tsb about it...today i bought maguires scratch x 2.0 and it did not work that great...i belive the tsb said use maguires #9...i was wondering if they are one in the same or if i should use something different...thanks rob
