[HOW-TO] Rezound Glass scratch repair

[a.mcdear]

So my phone fell out of my pocket, screen directly landed on a rock on the ground. There was a nice scrape right in the dead center of the screen.

I found a product called 3M "Perfect-It III Trizact Machine Glaze", or otherwise known as "3M 06070". It is an aluminum silicate based polishing compound for removing swirlies from extremely high-gloss automotive finishes. The stuff is approximately $65 for a quart size from NAPA auto parts. For those who aren't aware, Gorilla Glass itself is an alkali-aluminosilicate, so this particular polishing compound is chemically compatible with the material the screen is made out of.
**Apparently Rezound is NOT Gorilla Glass (confirmed by Corning & HTC) but must have a very similar composition**

It works absolutely beautifully. I started by applying it with a polishing cloth and rubbing by hand, but I switched over to a polishing cloth Dremel tip in my cordless drill at low speed. Approximately 45 seconds worth of polishing the screen with the drill and scrape is hardly noticeable now. With a little more careful work, I believe it will be completely gone!

Unfortunately its expensive. $65/quart is really not that bad though, when you consider that most polishing compounds that are sold specifically for glass screen repair cost as much as $30 for 8 ounces, and in my experience are less effective than 3M 06070.

I hope this helps anybody with a damaged glass on the screen. Best bet is to just get a screen protector. Not having one is a potentially expensive mistake..

**NOTE**
While this does work on the Rezound, I would NOT attempt this on any other glass screen unless you can verify that it is real Gorilla Glass or some other aluminosilicate glass.


Alternately, if you prefer to simply replace the entire glass/digitizer portion of the phone, I have found one available online (for cheaper than this polishing compound too!) here at this site: http://www.gogotoshop.com/product_info.php?language=en&currency=USD&products_id=4896

**NOTE**
DO NOT USE THIS ON A SCREEN WITH ANY OTHER TYPE OF GLASS OR COATING! THIS METHOD IS FOR GORILLA GLASS SURFACE REPAIR ONLY!

Why are you posting this in the Rezound forum? I was under the impression that the Rezound does not have a Gorilla Glass screen. Is the Rezound screen also an aluminum silicate compound that just isn't the Gorilla Glass brand?

I believe that is the case

Good to know, thanks!

As I understood it, HTC only uses gorilla glass on recent phones. If it isn't the case... then I apparently have no idea what glass is on the Rezound but it must be similar chemically because this works. I tried this on two other screens as well: Asus Transformer (which definitely IS gorilla glass) and it worked beautifully, but on an old iPod Classic from 2008 (not gorilla glass) it made the screen all hazy.

So, I guess if the Rezound doesn't use Gorilla Glass, this still works quite well, but for a reason I don't know (because it definitely does not work on other types of non-gorilla glass)

OP Corrected. The Rezound IS NOT GORILLA GLASS. Apparently its similar enough that the process still works.

Do you have pictures before/after? I would be interested in perhaps doing this. I've had my phone naked since Day 1 and I've managed to get a few annoying scratches here and there.

Funny thing is, I treat it no different than my EVO 4G (gorilla glass) and over 2 years I've never had 1 scratch in the EVO even when dropping it. I always keep it in a pocket free from any coins, keys or anything else and never place the phone face down on tables. I guess the Rezound just has a significantly less durable screen.

No I didn't take pics at the time honestly, and now that Rezound is gone cause it was warrantied for another after a hardware failure...

I did notice that the glass on the rezound is not smooth... It has some warping on the top surface that you can see when light reflects off it....the area I had used the rubbing compound on became flatter and smoother, and thus was also slightly visible in the center of my screen when a bright light reflected off the surface as mentioned before.. however this was the only situation in which it was noticeable. When actually using the phone, it was impossible to notice - you had to actually look specifically for it.

Anyway, I agree the glass on this screen is much lower quality than real Gorilla Glass. I honestly can't believe HTC would cheap out on a part as important as the screen glass, but they did it. The link I posted has an identical glass to the original one, and I went ahead and purchased one in anticipation of ruining my screen again when I inevitably drop my phone or accidentally put it in the same pocket with my keys or some pocket change and scratch it up again.

However I would note that while the polish compound worked, I would only use it on light surface scratches now, and not the deeper scratches like the one I initially repaired when I started this thread. This is because of the not smooth top surface like I already mentioned. If the scratch is deep, enough polishing will fix it, but will leave an area that you will be able to see when light reflects off the glass due to the glass not being smooth initially.

iPods (at least the pre-Touch, full size ones) have plastic screens.

No, my old iPod mini had a glass screen
I remember breaking it in accident then just popping it out

You're apparently under the mistaken impression that your "iPod mini" is a "full size" one. It isn't.

Awesome info! Thankfully I work at a car dealership so I'm going to have to talk to our detailing department and see what price they can get this at

Thanks again OP!

I just got some on Amazon for $46.96

How did you get on? read on Amazon a comment saying it didn't work and in fact made the screen dull

It didn't really work. But it didn't dull my screen.
