Fresh out of the coke bath. Wiped clean with a paper towel. For sure removed some surface rust on most bolts. But didn't do a lot to the two bad ones.
Bolt heads. Shiny.
Afterwards I tried some of this...
Next I hand sanded the bolts with 120 grit sandpaper, then used "0" steel wool. Degreased with simple green and applied the gun blue. I thought I did a pretty good job prepping but I guess not. The gun blue turned out pretty bad (splotchy) and only covered the bolt head on most of them. The instructions said to cure the gun blue by dipping in water. Well since most of the metal was still exposed it just started to rust... so for now the bolts are back in coke soaking for tonight to help prevent any more rust from forming. not sure if I'm gonna try gun blue again. Maybe sand them and just use satin black rustoleum. (i know these bolts aren't originally black but I want them to be) I'm a noob, but I'm glad I didn't get a chemical burn or kill myself on the positive side.
