The reason professionals charge so much to spray urethanes etc, is not only due to overhead but also for worker's comp., proper training, equipment and to ensure a quality finish. Always check out the MSDS for all materials you work with. Breathing glass from fairing causes silicosis which is far worse than asbestosis (exposure to asbestos). Both lead to Pulmonary Fibrosis or scarring in the lungs. Lung tissue is soft and moist. Scar tissue is hard and cannot hold moisture. My Grandfather died of Pulmonary Fibrosis, his lungs would bleed and were full of holes because the scar tissue couldn't expand and would crack. Its a sad thing to see someone gasping for air just from walking up a few steps. He was in his mid-70's. Be sure to wear a HEPA filter when grinding, especially glass. Galvanize poisoning can be fatal as well. I work in the HVAC industry, Sheet Metal and galvanize poisoning can occur from grinding as well as welding. If you feel sick after grinding/welding galvanize drink some milk as the calcium will bind the zinc in the galvanize and seek medical treatment from an Emergency Room. If you are having difficulty breathing make sure to call 911 and activate EMS. I used to be an Emergency Medical Technician years before getting into construction. Breathing fumes from "cold" galvanize trade name ZRC can also cause galvanize poisoning. You need to wear special protective gloves when brushing or spray bombing cold galvanize and be in a WELL ventilated area. BE SURE TO GET THE MSDS FROM YOUR DISTRIBUTOR AND READ IT FOR YOUR SAKE AND THE SAKE OF YOUR LOVED ONES. Improper disposal can lead to exposure of your family, children and pets are especially vulnerable and can suffer fatal consequences. Don't mean to beat this to death, just want everyone to enjoy the hobby. SAFETY FIRST. GOD Bless and take care all, Greg
