I used this to cover Shitake mushroom plugs I put into logs to eventually have a mushroom crop. I melted it in a small crockpot I had lying around. It melted promptly, and I painted it on with a paintbrush over the plugs after I drove them into the logs. I also painted the ends of the logs, the idea being to keep as much moisture as possible within them.
The wax did what I wanted it to, at a reasonable price. Couldn't ask for more.
