GYEON Q²M WaterSpot, Car Water Spot Remover for Paintwork, 500ml

Bought this as my black ceramiced Audi RS3 would show water spots on the boot roof and bonnet after each wash and would really annoy me !!! I wanted something that wouldn’t harm my ceramic. Washed the car, sprayed this on liberally, left a few seconds, rubbed it around with a micro fibre cloth, waited a few more seconds, rinsed it off, then washed that panel again, rinsed and it was gone. Very happy with it. It said not to use on glass, which is awkward when spraying and it going on the glass (overspray), so I made sure the glass was heavily wetted before spraying on the panels and heavily rinsed and re-washed the glass. I’ve had no issues doing it this way.

Did not work for me.

Very good works well on fresh water spots but in the heat at the moment don’t let them dry

It's fine on a car, with good paintwork, but we also used it on our old campervan and it effected the old paint with quite badly. We had to apply a series of Autoglym products, twice, to get it back to where we started, so just be careful. Worked well on the much newer car though.

Five stars for Gyeon as always

Didn't work as well as I'd hoped

After reading the reviews I thought this might remove some tough water marks but it didn’t, might work for some light marks but nothing will beat a proper polish.

Love this product. Bought a used black Mercedes back in May which had bedded in water marks all over the roof mainly and a few on the bonnet. Removed them all with ease. Great product.

Understand this; water spots are minerals that are etching their way slowly through your clear coat. This product like many others is going to use an acidic primary ingredient to dissolve the spots (which are minerals) With this I had to let it sit on my paint (cool area in the SHADE ONLY) I agitated it in with a cheap small thin microfiber. You want the entire treatment surface to look wet, as in it’s being coated with 100% surface saturation. If it looks like it’s beading up or clinging together in clusters; you have wax or another sealant preventing it from covering how it needs to. To solve this you need to either IPA wipe or use a paint prep solution to clean off your protectant before it will truly cover the surface and do its job. From that point you should be able to use your agitation microfiber and massage it into the area like lotion - light pressure! (It’s primarily a chemical means of removal, not physical.) You may need to do this 2 or 3 times depending on severity. Now here comes the problem people or even you may run into; those old water spots, if left untreated for a very long time, may have already literally eaten their way through your clear coat and made a permanent crater… even after minerals are removed your WILL still see this if this is the rare case! I just used this on my personal vehicle and it works very well. The photos I posted are the only ones I have a before and after of, but I had to treat my whole vehicle’s top surface. I am a professional detailer and run my own service company, this is a great product and I will continue to use & recommend it.

Lo compré para eliminar marcas de agua (salitre/cal) en las ventanas de un coche. Lo primero es que aplicas con miedo, porque las instrucciones dicen que hay que eliminarlo antes de que seque, y luego aclarar bien. Un producto con tan poco tiempo de acción pienso que no puede hacer milagros. No sé en otros casos, pero en el mio el efecto ha sido nulo. Dieron mejor resultado el vinagre y el bicarbonato. Creo que me inclinaré por el pulido para dejarlo bien.

Awesome!!! I had terrible water spots. Took it to my detailer after attempting several water spot remover product to no avail. He couldn't get them out and recommended polishing. This product did the trick. Awesome. Saved me over $1000.00

Trop cher et peu efficace

Really good product
