Fibre Glass Pond Application

I wonder if someone could help...

I have seen fibre glass successfully used in the designs of garden ponds and
was hoping that you might offer some advice of what materials and resins to
use.

The finished pond will consist if a raised water feature which will overflow
through a small waterfall into a shallow stream (12 inches wide x 12-15 feet
in length) and drop to a pond (surface 6 feet x 10 feet; depth: varying to
max of 5 feet). Structurally, underlying everything will be cement blocks
and slab, which is to be waterproofed and capped with ornamental stones.

From what I recall the application called for a rendered surface (near
smooth) on which they applied 2-3 layers of fibre glass with a dark coloured
pigment for effect.
