I’ve recently rebuilt and expanded my sundeck (15’x14′).  It’s 5/8″ T&G ply on 2×8 joists 16″ oc.  The joist span is 11′ with a 2.5′ cantilever, the beam is 6×10 (built up) on three 6×6 posts.

The previous deck was surfaced with vinyl but I wasn’t particularly happy with its performance over the 6 or 7 years of its life.  So I’m pondering whether to use fibreglass this time around or go back with vinyl.  I’m looking for feedback on fibreglass’ performance, ease of DIY installation, potential failures down the road, color gelcoat vs resin color coat, ???

Heck, I’m even open to alternatives other than vinyl and fibreglass.

Thanks in advance.
