I used Meguiars for the first time this past weekend and All I can say is WOW! I waited because my cladding was in good shape (so I thought). The difference was like night and day. My fiance who HATES my VX cause I love it so much, actually commented on how good it looks (and smells LOL). So even though I have a full bottle of Mothers, I'm stuck on Meguiars.
