## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Easy to use, straightforward direction and application.
  

*by M***E on Reviewed in the United States on 24 June 2024*

Geon will remove job hard water marks if you "spot" them soon enough. Does a very good job of reducing the mineral etchings from those latent neglected "spots." You still need to polish those to reduce their affect on the clear coat.Amazon was the carrier, and again delivered a 16oz. plastic bottle with a cracked cap. The Inside of Amazons tare open plactic bag was sticky, and all of the bottels graffics were desolved.

### ⭐⭐⭐⭐ 







  
  
    Effective for relatively new water spots
  

*by D***L on Reviewed in the United States on 29 July 2024*

The Opti-Coat MDR is a good choice for gentle water spot removal of spots that have not yet etched into the paint. It's a very gentle formula and not all spots will be removed on the first application. A few tough spots I tried required 3 or 4 applications to fully get rid of, and if that didn't work they'd need to be polished out anyways. I wouldn't use this for polishing preparation, but the gentle formula is perfect for removing spots between washings.

### ⭐⭐⭐ 







  
  
    Didn't seem to do much on old spots.
  

*by R***X on Reviewed in the United States on 3 May 2024*

It's OK...but maybe I was hoping for a miracle.I tried it on some hard water stains on glass as that's going to be the easiest to test and photograph.Used per directions- used a new microfiber foam pad applicator. Wiped on and let sit for about a minute.Wiped off.Now, it's not that easy to wipe off as it's a bit sticky when I tried wiping off.Only noticed a slight difference.Tried again in same spot.Let sit for a minute.Wiped with microfiber towel. Looked the same.I did try a recently dried water spot, wiped, let it sit for 60 seconds then wiped off. That did work.So my advice is - use on freshly washed vehicle if you have hard water and spot treat.For old water spots - it didn't completely remove them -  just made them look a bit less noticeable.
