Just a note, you are going to be reading and get confused with all these products!! lol. drove me nuts over the past 4 months. But the Junkmans vids really helped.
I'm still sticking to 10% products and 90% technics/elbow grease !
I went with the Meg's 105/205 and Orange and White Hex logic pads. I'm extremely happy with the results for a novice. I'm getting random complements even when the car is dirty!
