W9 Water Spot Remover

Does the job! I had my detailer use it on my car and man it took all the water spot away. Its also safe to use on ceramic coated cars. Gtechniq is simply the best!

Great product my paint shine so great

I applied the product 3 times. Still see spots. Not what I expected.

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 :)

Works but trigger on bottle broke first time using. Smells like pure vinegar.

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.

This product did not perform as expected. Followed instructions as noted and repeated the process twice and the spots still remained. Highly disappointed and dissatisfied.

Product actually does what it claims to do and that is it removes vehicle water spots. Apply with micro cloth on warm surface then remove with clean micro cloth with 70% isopropyl alcohol on a micro cloth. Then follow up with wax. Removes water spots from clear bra as well..

Awesome product. Does what is says on the bottle.

Great product at a fair price

Removes 90 percent of water marks on red paint work.

Used product on my windscreen. Etched a permanent white stain that cannot be removed. Contracted Gtechniq. They told me to buy G4 and perfect glass. I did. It made no improvement. Contacted Gtechniq again. They arranged for a Gtechniq accredited detailer to machine polish it out. It made no difference. I pointed out their product states clearly on the bottle as '100% safe' and 'works well on glass' I requested Gtechniq replace my windscreen. They declined and told me I hadn't used the product correctly. Ridiculous. Very very disappointed in this company. Do NOT buy!

Excellent, followed the instructions and quickly removed residual water marks from all the paint work
