[DIY] "Brushed Metal (-esque)" Battery Door

It seems like the #1 complaint about the Nexus S is the shiny plastic battery door- well I, like others, decided to do something about it. I started by seeking out a can of the now-ubiquitous, slightly infamous PlastiDip.

No luck.

Instead, I wound up with a similar product by 3M. On the downside, it sucked. The upside? It was not possible to "peel it off," which is often mentioned as a benefit [and the main shortcoming] of PlastiDip. Removing it required long soaks in acetone, and a lot of scrubbing & scraping. [I do want to note, however, that the 3M undercoating spray could probably work quite well for someone with the time to figure out when, after spraying, to roll the surface flat].

Anyway, here's what I ended up with / resorted to / etc. It looks fantastic!

Steps:

1. Wetsand like crazy with 60 grit paper. The shiny black layer is surprisingly resilient. Once you're through it in one spot, you'll see what you're trying to achieve in this step.
2. Wetsand like crazy with 150 grit paper. The goal here is to smooth out the inconsistencies left by the 60 grit paper. Note- you are not trying to eliminate all striations.
3. Wetsand in a linear fashion with 150 grit paper.
4. Sand normally in a linear fashion with 150 grit paper.
5. Rinse.
6. Dry.
7. Rub some chapstick on it like it's car wax. Buff it like its's car wax. Repeat like it's car wax. Or maybe use car wax(?).
8. Admire your handiwork.
9. Get angry with Google for these stupid Justin Beiber commercials.

That's it! Takes very little time.

Be reckless. You're getting a Nexus Prime soon anyway.

Looks awesome man, when my cover gets really scratched I will do this.

Thanks for the positive feedback! The surface ends up feeling a lot like a soft-touch, rubberized finish, btw.

That reminds me- one huge "plus" of going with this method over PlastiDip is that any future scratches can be fixed by a simple swipe of 150 grit.

Now if I could just find a Google or Nexus stencil, I'd spray it on with the 3M stuff and be super happy.

Damn that looks amazing I think I'll buy a 2nd battery cover just to try it.

You should spray it with a matte clear coat.

Thanks! I was thinking about covering it with the Invisible Sheild Dry back protector, but I'm not sure it's worth the money considering any damage can be buffed out in about one minute

Ehhhh, who am I kidding? I'll probably do it.

Ok, I think I will try soon.
If I understand fine (my english is not perfect):
- use 60 grit paper (is the most coarse-grained right?)
- use 150 grit paper
- wash and dry
- use a kind of product I don't understand this

PS: do you have hq pictures?

Make sure you sand under warm, running water, adding soap occasionally and changing your sandpaper frequently. This will make the process a lot easier. Only sand with the surface dry at the very end, to put the final finish on the plastic.

If you can, sand in vertical motions the entire time. I became impatient and used the 60 grit in a circular motion to get through the layer of shiny black plastic. This didn't damage the finish product, but it meant I had to spent more time sanding out the curved lines I had left.

Chapstick is an extremely common product in the US; it's just a waxy substance meant for chapped lips. The type of wax you would use on a car would work just as well. To be honest, I don't think this step is even necessary, but it seemed like a good idea.

I will add more detailed pictures to the original post in a few minutes!

I just tried it on mine and it looks great! I had a spare battery cover that I wasn't using, so I said what the hell. I still need to do a bit more sanding to get it perfect though.

Thanks for the tutorial! :D

Wow. This looks fantastic. I am actually considering doing this to my "limited edition" Nexus. Perhaps I should try to find a standard cover first, though...

Nice! It looks great man. I'm really glad someone else did it and was happy with the result.

The best part about doing this is that it actually makes the phone more scratch resistant; I don't have to worry at all about sliding it in and out of my car cradle or anything like that anymore.

How long did it take you? I had to kind of ballpark the amount of time this requires since I had no idea what I was going for when I did it myself, haha.

Thanks! And I know! All you would have to do is just buff any scratches out and you're fine.

It really only took me about 45 minutes overall. The chapstick idea was genius. That really helped with making it look polished. It almost feels like wood lol.

Looks fantastic!
Can you explain me exactly how you do?

Guys about chapstick, do you mean the Lip chapstick? :confused:
If you use chapstick it greases all the cover no?

I pretty much followed the instructions that Aardvark gave. I wet sanded with 60 grit until most of the shiny polish came off, and then finished all the corners and edges by wet sanding with 150 grit.

Then I dried it off and started dry sanding with 150, trying to sand as straight as possible. Then washed with soap (because my hands were black as well) and dried.

Yes, it's lip chapstick. It looks greasy at first, but once you rub it in for a minute and let it dry, it looks perfect.

Hope that helps!

Sorry, another little question:
I have to buy the sandpaper.
How much I have to buy?
I mean it needs a little piece of sandpaper or it consumes a lot?
