Alright fellas, the fiddy had some HORRENDOUS waterspots etched on the glass all the way around the truck. With a little elbow grease and power tools, i haz no more. nothing but shiny spot free glass.

Tools:

2000-3000 grit automotive sandpaper
Water in a spray bottle
Compound (heavy cut or medium cut)
0000 FINE steel wool
Clean microfiber towel
blue painters tape
DeWalt buffer
Wool cutting pad

put a tape line down the middle of your window to establish a 50/50 line to help see if the product/technique is working for you.

Wet sand the glass with the sandpaper all over.
Then Dry

Now put some compound on your steel wool and go to town on the glass. use your palm to put flat even pressure on the wool. Then use finger tips to get into corners of the window

Once that is done, use microfiber to wipe off compound and check progtess/results.

Put compound on wool pad and go to town on the glass. I used 2400-3000 rpm on the buffer intermittently. wipe product off to see that you are actually removing spots. once glass is done buff to a shine with the microfiber.

Below are the pics:
