What is the best product for a clear-coat finish on an exterior wooden deck rail?

Spar varnish.
Shellac.
Lacquer.
Waterborne lacquer.

The correct answer is: Spar varnish.

Spar varnish is the best option for a clear-coat finish on an exterior wooden deck rail because it is specifically designed for outdoor use and can withstand harsh weather conditions and UV exposure. This makes it more durable and long-lasting compared to the other options. Shellac, lacquer, and waterborne lacquer are not suitable for outdoor use as they can easily deteriorate and break down when exposed to moisture and sunlight.
