Finally after 3 years of trying to get rid of water spots on my windshield and side windows I found something that works. I was getting headaches driving my truck because my eyes kept on focusing on the water spots, especialy at night. This was the last try before I slammed a hammer through the front windshield. Meguires #4 Heavy cut cleaner and an orange cobra cut pad on my G100 D.A. speed 6. It took 3 pass to get the windshield done but now it looks like a new winshield. I have to work on the side windows some more but they are coming along also, I lost day light yesterday but will finish up in the next few days. Ive tried everything people had suggested here like, Bonami, stove top cleaner, vinger,kaboom,mothers chrome polish,clay,stoners,steelwool 000,windex,Meg #2,razerblades,other glass cleaner, bar cleaner, and the list goes on. Yesterday my G100 paid for itself just in the cost of a new windshield. If anyone has bad water spots just get the Megs #4. Im sure a rotory polisher would have worked a lot better but I dont have one.

 

Is that just for spots on the windshield/windows? Do you have bad spots on the paint as well?

No bad spots on my paint, I always kept up on the paint but the Megs #4 is for paint. For me #80 took care of all my paint needs, but on the Megs scale of 1-10 its an 8 on cut.
