[RE-wrenches] Painting anodized rails?

[frenergy]

Many times when we get close to the end of a 'rail run', mounting PVs, 
when the rail's end is still far enough away from the second or third 
from the last PV, we will measure exactly where the outside edge of the 
last PV will land.  We then undo 1 or 2 of the bolts attached to feet, 
pull the rail away from the roof a few inches and cut it there with a 6" 
cordless 'skilsaw' (clean cut and very little vibration using carbide 
blade) .  Because we use PLP P8 rail (formerly DPW) we re-bolt rail to 
feet and secure the very last PV's  edge with their back of frame flange 
clamp, P/N P8-ECU.  All this ends up either flush with or inside the end 
of the rail/PV edge.

             Does painting new or anodized aluminum qualify for the 
tail-light warranty?

We have been painting mill finish aluminum flashings for one large 
repeat customer, and I can tell you that it doesn't look great. I 
strongly question the long-term efficacy of this practice. But the 
customer is always right... so we do it despite our protests. I would 
refuse for a one-off job. I only do it because we have a contract for 
hundreds of homes and my bargaining position is not good.

How much rail is really exposed anyway?  We use Unirac's pro style end 
clamps the rails don't really stick out much anyway. Or use BoB panes 
with black rails and clamps.

A customer has asked that I look into painting the exposed parts of the 
anodized rails on their roof mounted system to more closely match the 
shingles. (New construction, we did not know what the shingle color was 
going to be, and I have to say, I did not ask). Has anyone any 
experience with this?  Thank you for any help. Chris
