B-C bluing & Rust remover took off most of the old finish
I kissed the surface with the wire wheel to remove the film left by the acid, now we can see what we are dealing with
The pitting was worse than I thought
note the pitting where the cylinder release sits, the release has similar pitting on the bottom side
And the sanding begins...I decided to start with 220 grit and sand in all possible directions. This way I can avoid taking too much metal and leaving any deep scratches.
From here on out the side plate and crane will be in place during any sanding or polishing
