I just finished this very project and got them mounted on my car this past Saturday. To remove the bright dip anodized coating I used Eastwood Company's anodized coating remover. It comes in a 16 oz. spray bottle and I used one whole bottle and less than half of another. I had to do the rocker moldings and the door strips. I let it stay on there a lot longer than what they say. It removed almost all of it and what it didn't was mainly around any sharp corners on the molding. However, it did make it easier to sand off. After I removed the coating, worked the dents out of it and sanded down the high spots, I sanded it all down starting with 220 then 320, 400, and finally 600. I polished it using an aluminum polishing kit I bought that came with a bar of red cutting compound and white polishing compound as well as the two different 4" wheels to use with a drill. After all that I finished it off with Autosol polish which I did by hand. After masking everything off and painting the black on them I'm well satisfied. They shine real nice and look good on my car. It took several hours but it was worth it. I bought these from another member here and I have a little over $400 in them total. I got a good buy in them. Now you can buy new ones for around $600 but you still have to paint the black on them. Might be worth it if you don't want to spend the time reworking originals.
