Chemical Guys SPI10816

Scanned online for one of the best for getting those spots of auto glass and it was consistently rated as a top product. And it does what it says. The thickness helps with the cleaning a lot, since you are usually working on glass that is upright on a car.

Really works

I've had water spots on my car windows for ages and nothing I tried would remove them. This took them right off and with relatively little work. I wore gloves and was careful not to get anywhere but the windows. Very happy with this product and I recommend it.

WOW

Wow, just wow. I'm getting some dings fixed on my car and needed to remove water spots so the fixed areas aren't noticeable, and this worked so well. Definitely requires patience and lots of microfiber towels, but it is well worth the time and effort.
