Gtechniq W9 Water Spot Remover for Cars, 8.45 fl oz | Advanced Solution Easily Removes Stubborn Water and Silica Spots from Bodywork, Suitable for Glass, All Paint Types and Vinyl

Had mixed feelings about ordering this to remove the water spots on my black pickup truck. I hadn’t realized that water spots were common after putting on a ceramic coat. But before spending hundreds of dollars more having it professionally detaiyto remove the spots I figured I’d give it a try. I first washed my car and towel dried it, leaving the surface slightly wet. I then applied the product and rubbed it in a bit (helped quickly) and finally buffed it out by hand with a thick microfiber towel. Came out beautiful. Lastly, I washed the truck again with chemical guys ceramic foam soap for ceramic coats and then thoroughly dried the truck. My truck looked like it was as fresh as when I initially had it ceramic coated. Needless to say I’m pleased with the product :)

I love this product between washes to keep my paint spot-free.It’s only meant for removal of LIGHT water spotting BEFORE it etches into your vehicles paint. Anything that’s too deep will require polishing/compounding.Don’t listen to reviews from those who say it doesn’t work - they believe the product is magical and can remove all spotting which just isn’t true.

Worked perfect

Was hoping this simple product would work on my dark blue Mercedes van as I watched it on a YouTube video. It had been ceramic coated, but developed bad water spots. nothing else removed (vinegar did nothing alone). It does take quite a bit of rubbing and applications. Each time the spots got less until the third application did take it off and looks great again. It was a lot of hand rubbing and product (will have to order more), but the detailer said they would have had to buff it out ($500.) and then reapply ceramic coat. Hopefully the coating is till intact and does bead up nicely after a ceramic detailer was applied after the w-9. So far, pleased even though a lot of work with carefully washing, drying and the applications. No way to tell without trying!

My husband's car was parked by a sprinkler, and we have very hard water, which left water spots horribly on the right side hood fender and partially on the door. I had tried vinegar and other products to try to remove it to no avail. We were told it would have to be professionally buffed out.I received this product today and used it only on the hood and the upper part of the metal between the driverside door and windshield. It completely removed the water spots!!You do have to use a little elbow grease if they are really stuck on there, aka baked on, but it worked and is totally worth the effort! I read comments prior to purchase, and the bad reviews stated it only smells like vinegar, which it does, but I can smell other chemicals in this bottle. As others have commented, this is more than glorified vinegar.

I've been a fan of Gtechniq products for a while, but this one just doesn't live up to the hype. I have some moderately difficult water spots on my car's windows and paint, and I was hoping this would be a simple, quick fix as advertised. Unfortunately, it barely touched the spots, even after multiple applications and a lot of elbow grease. It seems to work well on very fresh, light spots, but for anything that's been there for a while, you're better off using a vinegar solution or a more aggressive polish. It's a lot of money for a product that only works on the easiest of water spots.

Great product

My black truck had to sit outside after getting ceramic coated. I followed instructions to not wash but lightly spray off for major things like bird droppings that could not sit on the paint.After the first was nearly 3 weeks later, I realized I had a pretty significant water spotting issue. Especially on the roof. Washing and light buffing did not help. After doing a bit of research, I found Gtechniq W9 to be highly recommended by several. I'd used some of their other products and the price was right so I gave it a shot.Magic. Significant mineral deposits that were not coming off came off immediately. I let the product sit for no more than 10 seconds, wiped right off and it vanished. Amazing. Highly recommend this product.

Great product but pricy

Worked amazingly well. Cleared off the several weeks old water streak running down my side mirror on my red Mazda

Does what it says on the tin, great product

Sadly this product did not get rid of the rain water spots on my car paintwork and made no difference at all.

Removes 90 percent of water marks on red paint work.
