Well I finished the slate repair's, now I'm starting to do a little staining, it was easier to do the stripping then applying stain. Here are a few picture's I decided to use Min-wax gel stain Hickory, this is just the first coat not sure if I will add a second not wanting it to dark.
 
Looks real nice.  I would send your rails to Mark Gregory.  He does the absolute best recalibrations on the planet.  He does them in a controlled enviroment with professional tooling that offers the most repeatable accuracy.  He also replaces the figure 8 (or 5) plates with insert nuts like on the diamonds.  You can really torque them down tight.  Makes a night and day difference since the plates become very loose over time.
