I painted the inside and out of the tray with Licorice and let it dry.
Then, I painted a coat of Onxy over the Licorice and let it dry.
I measured out equal amounts of the EnviroTex Lite® resin and hardener.
Mix together and stir for 2 minutes.
Pour into a second cup and stir for 1 minute.
I poured this into the bottom of the prepared tray. I let this set up for about 10 minutes then.
I added the shells where I wanted them to go. I used a lighter to remove the air bubbles that rose to the top and let this set for 12 hours. Then I mixed up more resin as above and applied it over the top and let it set for another 12 hours and repeated with a third coat so that all of the shells were covered.
