I called around to some testing labs. I spoke first to a local company in the
Philly area, but the guy was not willing to do a freebie...Philly Attitude.

I then spoke with a company in Plainfield, IL that is willing to spend a few
minutes on the project!

If there is someone on this group that lives near Plainfield, IL (north of
Juliett) and is willing to drive their trailer for some testing, please
contact me directly for the company contact.

Or maybe someone out west could pursue this with a local company there.

With a little planning, we could test a few different materials. Go out on a
sunny day, get a reference reading, then test in the trailer. Perhaps also
make a small box on which we can put different covers such as tin foil, paint,
wood, etc and measure the UV ingress.

Let me know!
