Morning I am wanting to route a 1/4 × 1/4 groove around the outside edge of a project drill holes into the edge from the side. In those holes will be led lights I will use a glue gun to seal the holes. What would be the best resin for the groove I will also color the resin. I think doming would be what I need since I will hand finish it down but not sure. Any help appreciated thank you and have a good day.
