[RE-wrenches] Painting anodized rails?

[cwarfel]

Thanks Bill, I am not worried about the rail warranty. My focus is to 
provide roof access for maintenance or firefighters, so that is why we 
extend the rail. The shingles can take a beating during any maintenance 
procedure and the extended rails provide a place to put one's feet 
without slipping.  These are RS compliant multimode systems, (dc). I 
could have thought this out differently, but the other options would 
have cantilevered the rail and I did not feel comfortable doing that. Chris
