After double-checking that you have all the materials you need, preferably on a workstation covered with plastic sheeting, you can begin. Polyester laminating resin is a sensible choice. It should have the consistency of maple syrup and provide 20 to 30 minutes of working time at 70 degrees before it begins to gel. It should harden within three hours and cure within 24. For this type of project I only recommend fiberglass mat, which has equal strength in all directions and can be used in multiple layers. Different thicknesses can be used for different projects, but a good choice for this type is 0.75 or 1-ounce mat. It should be cut in 2" to 6" strips and shredded into square or rectangular pieces with frayed edges, which allow for better layering. Some areas will require triangular or arc-shaped pieces. Be sure to prepare all the necessary mat before applying the resin. Also have some acetone handy in a plastic quart cup. View Related Article
