Vibratory Tumbler

Well previous to the tumbler, I had some parts from under my car that I sand blasted, they were a mildly rusty and lightly greasy. I spent some time in the blast cabinet to perfectly clean them followed by submersion in a bucket of denatured alcohol. Then I set them in the sun to evap the alcohol, followed by the blackening procedure. They have been sitting in the sun for a couple days and the "sealing oil" had dried to a matte sheen.

Here are the after pics. Dang, no before pics.
