<VV> White pushrod tubes

[Dave Morris]

I'm sure NASA will be pleased to hear that they can change the colors they 
have been using.  And I'm sure all of us who are building aircraft that 
have to be painted white so they don't overheat will be pleased to hear we 
can now paint our airplanes a different color.

On the other hand, I'll bet I can come up with a ton of references in the 
next 2 minutes that say white reflects heat better than any other 
color.  I'll bet anybody who knows how to use Google can too.  To wit:

"On a 90 degrees F / 32.2 C clear sunny, day in Austin Texas, a white roof 
had a temperature of 110 degrees F / 43.3 C, an aluminum coated roof, 140 
degrees F / 60 C, while a black, single ply roof, a temperature of almost 
190 degrees F / 87.8 C (yes, one hundred and ninety degrees Fahrenheit, 
eighty seven plus degrees Celsius). "

etc. etc. etc. etc.
