How will this color last before fading when exposed to southern sun all day? Too expensive to need replacing every few years b/c of fading.

Wondering how your deck railing is still holding up if you did choose the charcoal color?

Hello, Thanks for your interest in Trex! A lot of our product is installed in the South including black railing, and we haven't experienced any significant fading either in the field or in testing. Thanks, Trex Customer Care Team
