No. "cold vulcanizing fluid" is just glue. Automotive patches have a special compound on the surface that's glued to the tire. The heat of the tire flexing causes the patch to vulcanize in place. I doubt that bikes generate that sort of heat. (Tube-type truck and car tires can sometimes have the tube vulcanize to the inside of the tire through this heat. That's why you use talc when assembling such a tire.
I've never seen the sort of repairs that the original poster is asking about. (I've heard of them, though.) I don't know if they're still made. I've my doubts. There are still heat curing tube patches available for the truck tire market. They'd work on a bike, but they're big and thick. You put them on with glue, like a normal patch, and then the tube is heated. A heat gun would be enough, heat, I should think.
