can these be polished? i seen on some imprezas they are sparkling silver, mines are dull sort of greyish colour. Im reffering to bits on dashboard like audio surround and vent trims.

I'd say it's been wrapped or an aftermarket job. I'm still sorting mine out after hacking into it to fit the screen. 

would you recommend any good stuff to try polishing them a bit ?

I'd say this is the best way, I have been talking to a mate of mine about having ago at doing this ourselves as a business. You can make it how ever you want it to look really.

 

oh hydrodipping, yeah its cool but unfortunately nobody does it in jersey :(
