Video of my first DIY Solar Collector Box using 300' Pex Coil

I'm curious on how you painted the pex.

I set in exact position the Pex Coil within the Box , angled the Box at the desired 30 degrees from vertical ... then painted the coils on the top and sides (and the bottom as much as i could by slightly moving the coils around) : I waited for the paint to dry then did it 2 more times until i had good coverage . I used Krylon Fusion plastic paint which the Mfg'r told me is good for 200 f. The paint finish hasnt dulled in the least after a few days of operation with the outdoor temp. being 95 f. in full sun.
