Sarnia's Ryan Roth would give the Sting the lead again assisted by Perreault and Theo Hill but Connor Corcoran would pull the Spitfires even again.
Daniel D'Amico scored the winning goal 31 seconds into overtime.
Sarnia centre Theo Hill said it was a tough loss.
"It's hard to fall short on games like that especially when you're going into the third period up 3-1. You just gotta find ways to win those games and move on."
Hill said "You can always find something good out of every game. A big part of hockey is staying motivated and confident. Going into the (Christmas) break I think you should focus on the good things and we'll come back stronger next week."
Sarnia's Langevin stopped 40 of 45 shots while Xavier Medina made 35 saves.
The Sting visit Flint next Saturday then host the London Knights Sunday afternoon before visiting the Knights New Years Eve.
