Nadeau entered eight NASCAR Busch Grand National Series races for T&G Racing in 1995. At that time, the Busch Grand National Series was considered NASCAR's feeder circuit, a proving ground for drivers who wished to step up to the organization's premiere circuit, the Winston Cup. It is comparable to Formula One's relationship with Formula 2/Formula 3000/GP2 Series. He originally signed to run fourteen season races. Nadeau moved to North Carolina that year on the advice of public relations worker Tom Cotter, and was on a budget of $200. He often went to Hendrick Motorsports to receive tips. Nadeau failed to qualify for his first career NASCAR race, which took place at Richmond International Raceway. Later that year, he finished twenty-first at Hickory, twenty-ninth at New Hampshire, nineteenth at the Myrtle Beach Speedway, twentieth at the Milwaukee Mile, thirty-first at Lucas Oil Raceway, and did not qualify for the races at North Carolina Speedway or Homestead-Miami Speedway.
