iPhones are scratch-resistant, but life throws some tough stuff at our phones. One MacRumors user, owning a phone that looks pretty beat, demonstrates the full process of restoring his phone with sandpaper and a new LCD kit.
The poster makes a point of noting that on most phones, you'll only want to use a rougher sandpaper to tray and remove 90 per cent of the scratches, not get to a completely clean and polished look — with the scratch-resistant coating completely removed — as shown at the full post. For those looking to completely refinish their phone, there's a very informative post on the technique of wet sanding, along with tips on taping up your controls and glass and polishing off the finished result. For those with cracked or deeply scratched glass, there's a replacement guide included, too.
It's a cheap process and not too much time, especially if you don't plan on upgrading to a new model any time soon (ha!). If you've discovered a similarly complete and thorough iPhone transformation guide, tell us about it in the comments. Thanks for the tip, NomadDNA!
