The inspector here wants all exposed plastic pipe painted with a paint
specifically labeled as 'UV Resistant'.
In case anyone runs into this: Krylon Contractor Door and Shutter. One
of their plastic-specific formulations. Gigantic inspector-friendly 'UV
Resistant' lettering on the cap.
The bad news: *no one* local had even heard of it. Found one
Sherwin-Williams store with a guy willing to look it up, figured he
could order me a 6-can case (given that Sherwin-Williams owns Krylon,
one would hope...) but then never bothered to call me back.
The good news: utilitysafeguard.com. Still had to order a case, but it
was here in a couple days, no fuss, no muss.
