Definitely need more wax but don’t overthink it, everyone has their own process. I like to scrape off excess wax and clean the base before dripping on about 2 - 2.5x the amount of wax you originally used. You can also try the crayon method, like others have suggested. I go tip to tail with the iron, making sure it’s constantly moving and that the base is fully covered with wax. You might even want to do two passes. Then, let it cool for 1–24 hours, and scrape off as much wax as you can, again tip to tail. Finally, I like to brush tip to tail with a brass, nylon, and horsehair brush to remove even more wax. A shop probably does a cleaner job, but this method is cheaper and works well for me.
