Restoration might not be the right word but here is a little info on how to cold black oxide your bolts to add a little detail and help prevent them from rusting.

The first picture is a rusty bolt (what I started with).

Second picture is the sandblasted bolts.

third picture is the bolts submersed in the black oxide solution for 5-10 minutes.

Fourth picture is the bolts submersed in the sealer (I know you can't see them).

Fith picture is what the finished product looks like after air dryin and then wiping them off (next day).
