I went through my local car wash years ago and my antenna got ripped off while going through. So now I just wash it by hand. I just put a new soft top on too and I was wiping the windows yesterday with a wet paper towel, and I noticed it left slight scratch marks! They're not bad but wtf...I wasn't aware that the windows were so sensitive. Also, the reason I was cleaning them was because there was bird shit running down the back window. When I wiped away the bird shit, I noticed it left little divet marks, almost like little dents, in the window.
I'm hoping they will go away, but I'm going to try and be careful when cleaning this thing from now on.
