Abstract
A method for protecting joined workpieces from salt or other environmental hazards is described. The method may include joining an end fitting into a driveshaft tube which results in a gap between the two. The gap may be cleaned and dried before a moisture protecting urethane coating is applied. A urethane coating may be sprayed on as the joined end fitting and tube are rotated together. The coating penetrates into the gap and extends laterally beyond the gap and is subsequently cured with an ultraviolet light source.
