Fellow builders,
I have just removed the radiators from my classic Europa. I spent many hours
combing them to bring back the original beauty.
Now - always striving to do something different - I was thinking of
repainting them white instead of blak. It would compliment the paint scheme
of the plane.
I was wondering whether white paint would massively affect the ability of
the radiators to dissipate heat. My gut feeling tells me that the bypassing
air molecule does not mind the color of the hot metal bit it gets heated up
by. But then again ... there was something in science class many years ago
about dark body radiation.
If it has an effect of less than 5 % I will go ahead and spray them white,
however if I lose 50 % of radiation-ability ... paint it black.
Yes, I did find hi-temp paint claiming to transmit heat well (instead of
insulating).
Please advise.
