Abstract: A protective covering for a fiberglass boom is disclosed. The present invention is particularly useful on the fiberglass boom used on aerial lift trucks used by electrical utilities and for other similar applications. The covering includes a polyurethane coating applied to the surface of the fiberglass boom. Polyurethane strip material is spirally wrapped over the polyurethane coating and bound to the polyurethane coating by the use of a solvent sealer, preferably tetrahydrofuran. A second polyurethane coating may be applied over the polyurethane strip material. The protective covering of the present invention provides resistance to abrasion, weather resistance, and maintains the dielectric strength of the boom. Furthermore, the coating is transparent, allowing inspection for cracks developing in the underlying fiberglass boom.
