I need to clay bar my car soon, and ive noticed that i have some marks on my rear window (i have a hardtop), that look like they will come off. I also have some of those black tar spots on my exhaust.

What im wondering is, is it safe to claybar titanium (the exhaust), and the rear window on my hardtop? Do i just do it the same way i would clay my car?

 

You can do the window fo sho! The clay gets off those nasty water spots. I dont see why you shouldn't be able to do the exhaust, but why. Get some neverdull metal polishing wadding and use that. It will clean the exhaust right up.

 

Yes PLEASE clay the glass. It will make the rain roll off like it has rain X on it without the Rain X troubles.

You should also use clay on your wheels before you apply your wax or sealant like Klasse All In One.

How to use Clay

 

and clay is great on the wheels and lower body parts...

to be safe, just be sure to either trash it after using on the wheels or mark it so you dont use clay that has been used on the wheels on the body-

 

Yes absolutely, you will notice a definite improvement on both surfaces. Glass is especially receptive to claying, like jon said, it will allow the rain water to sheet right off as if you applied rain-x without having to put up with the rainx haze that it creates. It also removes all the little particles that become imbedded onto the glass just like it does on the paint.

A helpful hint that someone once told me about claying the wheels,exhaust etc. If you ever drop the clay bar onto the ground while working, which is pretty much the most frustrating thing ever, instead of trashing the whole bar, reserve it for use on your wheels and metal instead.
