  • What does oil do?

    After dyeing and sealing parts, I coat them with oil. I've found that it helps give more of a gloss finish to the parts. I stumbled upon the benefits of coating anodized parts with oil accidentally when I was machining a part that I had anodized, and since then I've been doing it ever since. What is the oil actually doing, and why does it improve the surface finish?

    Oil, wax, armor all, and lots of other stuff have been used to improve the surface gloss. Feel free to experiment, if you don't like the results, you can remove it with a solvent.
    I didn't use any post treatment in my paper, because I was trying to get an undistorted view of the anodizing and dyeing results.

      The oil/wax/whatever doesn't penetrate the anodized coating if the piece has been properly sealed. It is just a thin surface coating which will improve the appearance (depending on individual tastes) and give it a sheen and it will appear to be deeper/richer especially if using black or other dark colors.
