Shielding Wires From Sun

[Anonymous No.1696604]

Got an exposed run of control wires for my evap cooler on my roof. The sun already ate through the insulation on one part and the wires are occasionally crossing, so my cooler doesn't always do what it's supposed to (ie pump runs when it's off).

Two questions:
1) What would you use to shield these wires from the sun? Conduit, paint, something else?

2) I need about 3 feet of thermostat wire, and the cheapest at home depot is $20 for 50ft. Anywhere to get it cheaper?

Sealtite ("flexible metallic weatherproof conduit") and maybe a weatherproof junction box.

On the cheap? Wrap it with several passes of electrical tape. Then worry about it in 10 years.

Sleeve it with carflex and paint it white

This stuff likely wouldn’t be affected by the sun, since ut’s basically designed gor use in ovens and stuff.
Galvanized armored cable should also not be affected by the sun, since the uv rays are blocked by the metal outside.
I presume there is also stainless armored cable that would work.
