Without asking the tree painters, it can amount to 2 guesses:
Sunscald prevention: the name being very misleading since it's freezing that finalizes the damage.
And Sunburn prevention: where the sunlight / energy finalizes the damage.
Too many people confuse the two, and almost half as many don't really know how to deal with the problems.
There are solutions though.
The painting method for the winter protection could be tested using two thermometers that were calibrated, and inserted virtually "skin deep" to see if it makes a difference.
One problem - I have not read any research that discusses "sunscald" from an angle of whether or not it's the sunlight (rather than just the warmth) that triggers cell activity versus just the temperature increase.
I just compiled an article on these two - sunburn / sunscald (not the only reason people whitewash). And I found the 2 problems to be among the most challenging to sift through the diversity of opinions and differences of information - even from reputable sources.
They all are in agreement that:
There is sunburn
There is sunscald
Solutions? Much longer explanation.
