we were just moving a queen sized bed in the apartment. you know how HK rooms are small. so it was big and heavy. made a couple of big scratches on the wall. about 3 to 4 inches long. any company in HK that works on this kind of things? any DIY kit that I can get? previous renter made a bunch of smaller scratches all over the place, but I guess we made a couple of big ones. should fix it for the owner I guess. thanks.
