Sanded and Primed

I sanded down the trusses of the truss bridge this morning, cleaned off all the remaining dust and then primed all the new brass truss plates.  I had only a small amount of red oxide spray primer left at this point so I decided to use up the rest of the can on the rest of the bridge trusses.  

You know...  some bridges are even painted in this red oxide color and left that way...  I don't think I'm going to leave it this color though.  I'm still leaning toward a medium to dark gray with it tinted slightly toward green or a light gray tinted more obviously toward green.  At the moment, I'm leaning toward the medium-to-dark gray tinted slightly green.  

I just remembered that I didn't do anything with the top cross-bars...  I really should sand them to get them ready for more paint.  Actually, I should sand them to get them ready to be glued to some stringers and diagonal cross pieces.  Then I can focus on paint for that top section of the bridge.
