My son's black 2009 Dyna had bad oxidation.
Never Dull and Mothers polish were not doing the job and I didn't want to disassemble the forks to do a nice polish job.
I sanded the entire fork surface with 600 and a Scotchbrite pad.
I removed the wheel, taped off the top of the assembly and painted them black with Dupont auto paint. They turned out nice.
There is a guy on ebay selling a vynl covering for the front of the forks.
$15 might be a deal to never fool with them again.

 

Done the FL's forks last year.
Sanded smooth (#150, 400, 800, 1000 if I remember right), over to buffing wheel, used black, red, white rouge. In real tight spots, I used the dremmel.
Finished with Mother's chrome polish and 2 coats of wax.
A day's work
Good for a couple of more years, at least..

 

Great job, man! Did you use a bench buffing wheel? What brand of compound do you use?

 

Ya, used riding buddy's old dual buffer with a home made reduction gear, spins at 2800rpm.
the sticks were from Matchless, if I remember right...

 

My one cent worth, Aluminum looks better than chrome on a Harley. Some things your suppose to work on. That being said, use the Dremmel as the poster said, but don't go a couple of years. If you polish any aluminum once a month you will get a finish that is the reason chrome was put on a bike to imitate. Best is you will know and others will to that you did it. Unless ofcourse your old and have trigger finger than by all means get chrome!
