West System does not dry clear and develops an opaque look when exposed to UV. It is a great laminating epoxy and sealer but cosmetically there are better choices
Several manufacturers, System Three comes to mind, offer clear, low viscosity epoxies which are used as a base coat under varnish in harsh environments. I use it as a base/primer coat on teak rails, hatches, etc. on my sailboat and it remains clear indefinitely in the sun.
I have seen West System turn pretty wood a foggy, baby-[bleep] yellow in similar circumstances.
