The 1993 season started with Paul co-driving with Moretti along with Derek Bell at the Daytona and Sebring endurance races in a Nissan NPT-90. The trio were joined by Massimo Sigala for Daytona, and were leading when the car began to experience engine problems, but it still finished sixth. Sebring proved kinder to them, as they finished second. Paul then switched to Gunnar Racing for a few races. He was able to take one last podium finish, a second-place at Road American, driving a Porsche 962 for Joest Racing.
