Metal Refinishing Options:
From left to right in all 4 pictures they have been completely cleaned of rust etc. and then have had a protective coating applied.
From left to right:
Option A, B, C, and D (option B is natural/clear coat and C is flat black)
The only difference between the left pics and the right pics is the flash.
Note the top pics reveal the true color differences better than the bottom pics.
Also when looking from across the room there is not a great deal of difference between any of them.
