How do I do it?
-
Just as it sounds, get whatever you are sanding wet and then sand it. ^-^
-
take sandpaper
get it wet
rub designated surface with wet sandpaper
can also do it pneumatically, but that might be excessive for keyboard applications
-
So...is it wet sandpaper and dry object, or dry sandpaper but wet object?
-
Wet sandpaper, dry object. Rinse and re-wet sandpaper, repeat.
-
Start with courser grit (low numbers) and gradually go higher in grit (finer) with water.

**** i started with 3600 grit does this mean i have messed up already?

3600? Do you mean 360? But anyways if you have started that high it is fine to do down because it probably didn't sand much off anyways. The higher grit is used to make it smoother, you use the lower grit to get off all that you want sand (i.e. paint, rust, etc.).

3600 is exceptionally fine sandpaper ... probably about as abrasive as regular paper lol.
You should be fine, just go back to a more coarse grit then work your way back through progressively finer grits. Anytime I've wet sanded something (mainly automotive stuff), I've soaked the sandpaper in water for a few hours before using. Then get the object your sanding wet, keep your sandpaper wet, and go to town and occasionally re-add/re-mist water.

my case is smooth though. i'll check the grit again, but it's definitely very fine.

Usually the best sand paper for wet sanding is one with a latex backing. I usually let it sit in soapy water over night before i start my project.

I have fine-grit sandpaper ranging from 1000 to 12000...
3600 is still pretty abrasive when used on plastics and far away from "mirror polished" (that's more like 10k and above).
It all depends on what material you are working on and what you want to accomplish, for polishing chrome 3600 would already be too rough I guess.
-
ok the sandpapers say 320h and 1200h. enlighten me!

It depends on what kind of material you are sanding, and what you are trying to achieve. On wood or aluminium, sandpaper up to 320-400 grit still noticeably remove some material. 600 to 1000 will start to yield a smooth surface. Above 1000, you're basically removing no material at all, mostly polishing.
Keep in mind that it is best to use grits in sequence, so that the next (finer) grit of sandpaper removes the sanding marks of the previous grit. If you use 320 grit on aluminium and then switch to 1200, it will take you more time and effort to get a smooth/polished surface than if you use 320-400-600-800-1200.
Water acts as a lubricant and makes it easier to sand and avoid big sanding scratches.

I'm going to question the idea of you starting to sand something before asking these questions... not trying to be rude, but I think you should really start asking as many questions as you can before you actually go and apply it on the case. And perhaps test out what is being recommended here on something before you go and do it on the case.

The water is more there to stop the sand paper from clogging with the material you're removing. Water isn't a very good lubricator.
Add some soap to the water if you want added lubricity

i shall get an array i guess. is sandpaper in around A4 size expensive?
i am only sanding a razer blackwidow tenkeyless haha. it had a matte surface
