Hi, i had the same problem with my B44. I contacted a friend who can re chemically blacken the drive shafts, they look like new again and so far have been great. He's also done all the metal on my Schumacher CAT 3000's and Turbo Optima Mid. Check out chemical blackening on Google and it should bring up relevant companies who can do it. The company i used was in the North East .
Regards
Lee
