[RE-wrenches] Painting anodized rails?

[cwarfel]

Thanks Jason. Ihave been involved with educating firefighters on solar 
as part of my work and access is always an issue. So, I tell the 
customer that we are going to extend the rails past the array with an 
attachment so that we can access the roof and so can others. They did 
not remember that. It has an RS combiner on the roofwith a switch. The 
roof pitch is 12/12 with a badly graded front that precluded a boom lift 
getting to the west part. The roof was about 45' above the ground. We 
worked with harnesses and needed the extra rail to work safely and not 
destroy the shingles.

I may try to screw an aluminum laminateto it. Will experiment first. I 
do think they will get used to it, but the rails are about 8" past the 
array do we could hit a rafter and not cantilever the rail. Design wind 
speed is now 140mph here.   Chris
