I'm surprised you say only occasionally you get exhaust gasses coming in. A few years ago I repainted one of my vans at my in-laws since they had a garage they were going to let me use. I forgot to bring some of my new seals with me and had to drive home (100 miles) with my head out the drivers side window. Without the rear hatch seal in place it was sucking the exhaust right back into the van. Jeff Stewart ----- Original Message -----
