Hello, I have created a water feature which is made up of a sheet of plywood with copper pennies on top, looks similar to a penny floor but will be mounted vertically with a waterfall protruding an opening. I am looking at the expo resin range on the easy composites website. I think if this was an internal project it would be the GlassCast 3 but I can see on the forums the GlassCast range are not recommended for permanent external use.

Is there a particular product which would be recommended for this type use. I live in the Midlands, UK so wouldn't expect temperatures to drop much below -5C. The feature will be in direct morning sunlight. Other than splashes the surface shouldn't be in direct contact with water.

Any advice would be appreciated.

Unfortunately we do not have any clear resins designed for that kind of environment.  You may well be better off looking for a driveway/path resin supplier to see if they do something clear with the UV stability and water resistance you need.
