Dave Juntunen made his foray into the automotive industry in 1996 by working as a restoration technician for Kirk's Volkswagen—one of the largest facilities of its kind in the United States at the time. He started out with washing and waxing, but his detail-oriented personality prevented him from cutting any corners. Eventually, he progressed to exacting tasks such as paint correction, clear-coat restoration, and wet sanding. He also studied stain, scratch, dent, and paint technology.
With this knowledge, Dave started his own auto garage for exotic and European vehicles, which he dubbed Top Gear Autoworks. He later founded Twin Cities Detailing, where he and two other technicians primp elite chariots such as Lamborghinis, Mercedes, and ancient Roman quadrigas. They offer everything from basic details to in-depth sessions featuring clay-bar treatments, Menzerna products, and a three-step polishing process. When they aren't washing roadsters, Dave and his team repair upholstery, apply tinted window films, and decorate façades with pin striping to make autos look slim.
