I've been somewhat perplexed as I've followed this thread, re-read
chapter 37 in the build manual, recalled the factory promotional pics
of a beautiful blue-bottomed specimen, seen pics of Thomas Sherer's 10
year old bird, and learned of several new Europas with extensive
underside painting in dark tones. In response to concerns raised, some
of the posts have seemed somewhat cavalier on a topic which, if
misunderstood, may have grave consequences.
If anyone can cite an authoritative reference (no anecdotes please) on
temperature/strength issues of the epoxies used by Europa which
challenges the color/temp chart in chap. 37 I'd love to read it.
I realize I'm free to paint my "experimental" plane however I choose,
but I'd like to make a "reality-based" decision.

Hi Fred,
I can't quote any authorative source but I was on the Europa show stand
when the wrinkles in the nose of the US demonstrator were discovered.
The plane had been standing on hot tarmac and the skin temperature
difference between the dark blue underside and the white upper surface
was astonishing.
As a result I immediately scrapped my idea of having dark blue wing tips
and decided that the guidelines in the build manual were very valid....
white or light tones are good - and the heat doesn't always come from
above!
Tony

Fred,
The temperature difference in colors on Baby Blue varies less than 5
degrees F. The darkest color is a light blue (thus the name). Like
Tony said, white or light...

Jeff...though I've yet to see it in person, your pix of BB with its
gradations which I'd characterize as a light blue very subtle "mist"
strikes me as an excellent solution for anyone wanting to add some
"chroma" to our otherwise white aircraft...Fred
