Honda Civic Forum - 2 questions

1. what prduct could i use to remove water marks?
today i found some paper thin water marks on the roof of my car. because last night i hosed down my car to remove all the salt... and i didnt dry it. today when i washed my car, i removed half of the left over water marks. I was pissed to see the were still there. so foolishly i took some meguiars quick detailer mist to wipe the rest of it off. that did not work that good. i whipped out some meguiars step one paint cleaner, and that didnt work too good either. I even tried putting on second coat, and wiped the roof down with a microfiber cloth when i was done! You can still see paper thin outlines of where the water mark once remained when you look at the roof. Does meguiars make anything for water marks? if not who does and what is best?

2. what prdouct could i use to keep my stock tires clean?
driving in this bad chicago weather always leave my tires white when i park it in my garage. Whats a good product that will condition and clean the rubber? Otherwise, regularly I just use a seperate sponge and car wash soap (gold class) to clean my tires, hubcaps, and wheel well.

thanks guys
