You can get rid of that burnmark easily by painting cover with a new, maybe more intuitive color than that gray. Just use a some fine grained sandpaper, (or as I did), first carefully use sharp knife (I used surgeon knife) to remove those rised stripes and then smoothed with sandpaper. And finally a new paint on it. I found that best paint was a normal aerosol-carpaint (with metallic touch of course.. =) They're cheap and they're very durable. I think I used something like 7 layers, but outcome was pretty. I also painted those soft side bumpers (or whatever they are for) with same paint. > So yesterday I decided to give it a try and clean the keyboard.

Same paint can be used to repair eg. defective display cable. ---------- Duo/2400 List, The friendliest place on the Net! A listserv for users and fans of Mac subportables.
