Repairing and refinishing car wheels is usually a behind-the-scenes job. At local specialist company WheelKraft NW, the staff usually work at the company’s Hazel Dell garage or out of the back of one of the company’s mobile service trucks. But later this month, WheelKraft’s refinishing process will be one of the main attractions at the Portland International Auto Show, giving guests a firsthand look at the many steps needed to transform a set of factory-standard wheels into a unique and customized set. WheelKraft has operated a booth at the auto show for the past five years, but this year they’ll be taking things to a new level by joining the team at The Garage, a show exhibit that recreates a fully equipped and full-scale auto garage on the ground floor of the Oregon Convention Center.
