Hi, thank you everyone on this board for your help. I have cleaned and oiled my machine. It is a Singer with with Tiffany decals. Per this board's suggestion, I bought Turtle Wax and was going to put a coat on. But then I hesitated. Is there a way to fix the crazed finish on the machine? Should I attempt to fix the crazing or just go ahead and "wax 'er up"? I value your opinions!!!!
