A better/cheaper option is to buy standard epoxy resin and hardener.
The same stuff used for fiberglass... Not polyester resin.

I bought some from the local boat dealership. I was making something that had to hold up under higher temperatures
and was advised that epoxy resin was the way to go over polyester resin.

It's crystal clear and pours easily. About the same viscosity as olive oil.
