Hmm, I seriously doubt they would not still be available.
Just a couple of miles. I fully expect it to fail but it just needs to get me home before Monday.(how far is home?) The cooling system is under high heat and pressure during operation. I doubt if epoxy would hold the coolant reservoir at any moment after the car's fired up. Also be careful of air pockets whenever you need to refill smart's cooling system. It's been a topic of discussion over possible head gasket problems later...
