I thinkthis problem is really only "solved" by using the coverings
suggested, especially it seems, aluminum jacketing. I will be going off
island in a week and I will have the chance to go to a store that sells
these products. I am hoping to put this system into HomePower, so, this
will be part of the article. Thanks for everyone's responses. I
hopefully responded to everyone off line. Stay tuned. Chris

Hi Chris, Your question certainly generated a number of responses.
While the field applied covering I mentioned certainly peeled off and
had the consistency of latex paint, I did _not_ perform an analysis.
There is outdoor latex paint which should have UV inhibitors, so
perhaps it really was latex. The original owner is gone, so no help
there but a paint manufacturer may be able to verify latex paint as an
inexpensive _and effective_ covering solution. What made this solution
stand out in my mind so well was the flex roof flashings, which when
unprotected become brittle (and useless) oftentimes before the ten
year mark. This painted flashing was just as flexible as a new unit
and as you are well aware, replacing a solar flashing is way more
involved than a plumbing flashing. I am aware of many manufacturers
that rebrand/repackage a common item as a solution for a very specific
problem and charge an outlandish premium for the common item in a
shiny package (sometimes not even a shiny package). Bill

Hi Bill, thanks. I did not think latex would hold up anywhere near
that long. Chris

Chris,
The fitted covers certainly provide a more finished appearance. One of
my customers painted the insulation (w/o fitted covers) with latex
paint and after 30+ years the insulation was still quite flexible. My
take away was simply that eliminating the sun (UV) effects paid off
big time. As I remember they used white paint.
Best wishes,

How about the white PVC jacketing? You can buy fitted elbow covers
and other fitted parts as well. Probably paintable in any color to
blend into location.
