The EAA has put a few of their SportAir Workshops on-line. I guess this was due to Covid but the advantage is that with the course being on-line I don't have to wait until a class is available nearby. This on-line version can be viewed at home on a computer or any mobile device and is available for an indefinite period. I took the Fiberglass for RV and Sheet Metal Airplanes course and it is over 6 hours of video training. It can be stopped, backed up and reviewed multiple times so for myself is the perfect resource for basic fiberglass techniques. It covers the different resins and fillers and has some nice projects to practice. I was concerned about the bottom windshield transition and this is one of the practice projects. The course also covers making molds and repairs.
