I need some tips from vert owners on how they are keeping their vert tops in good condition. Specifically, I have some dark smudges on my vert where the top folds down, right rear, passenger side. I never lower or store my vert when the top is wet. The smudges are kind of greasy. I know you aren't supposed to do any spot cleaning. Okay, the truth is, it's really not that noticeable but I KNOW it's there and it's driving me batty. :eyebulge: Are there any special products or should I just keep using my regular car wash stuff (Mcguires)?
