Polyester resins are the most commonly used resins in the marine industry. These resins are marine grade hardened with mekp. When working with these resins it is advisable to wear gloves , eye protection, and a chemical respirator. These resins can be used with all types of fiberglass, except the ones on fiberglasssite that are epoxy only. Polyester resin can be used with carbon fiber, urethane foam, and core materials, but not styrofoam. Polyester resin is rigid when cured.
All of our resins are sold with wax ( and mekp hardener) in separate two ounce containers. Wax and mekp are included in the purchase price !
When polyester resin is used without wax, it dries with a tacky surface that allows you to add a second coat without sanding. If you add wax it dries to a smooth , slick , not sticky , non tacky hard surface.. (this thin wax layer must be sanded away before painting or adding another layer of polyester.)
