Meguiar's Extreme Marine Water Spot Detailer - Hard Water Stain Remover that Offers Additional Shine and Protection in One Advanced Marine Detailing Spray - Non-Abrasive Formula, 32 Oz Spray

Works well

This stuff works great! It is wonderful in the shower too, even though I got it for my boat and jet ski.

Not impressed used on a pontoon with water spots. Didn’t phase them.. Sorry for review but didn’t work for me .

easy direction, works great, highly recommend for all boaters to give this a try

I know this is a marine application but I used this on my 17 F 250. It had good ole Texas hard water spots from top to bottom. After spending all day with a clay bar getting about 2/3rds done I thought there must be something better. After reading some positive reviews of this product I figured what the hell. Ill give it a try. I tried spraying on some on the windshield. I gave it about 10 seconds and wiped with microfiber. The spots were completely gone. Not even the ghost outline left as I looked back through the windshield. It worked just as easy on the paint as I did my tailgate in about 1 minute. I would have taken over 30 to clay bar it off. I was wishing I had it before I spent 6 hours to only get 2/3rds one. I would have paid double the price. Once again Megs hits a home run

Got water spots off the good of my car but doesn't do anything for my windows

Works way better than boat drip. Looks amazing after a wipe down.

This product is the greatest product to use on my kayaks and my pontoon boat. Highly recommend this product to anyone.
