Yes in fact I bought this car expecting it to be a disposable car because I can't do a real car search until the summer. Look at it this way: suppose I have my mechanic replace the head gasket, the calipers, the rotors, the tires, and do an alignment... Then I've spent $2,500 to $3,000 or more (Boston prices!) on a rust-infested 1993 hatchback that still would have a giant dent in the quarter panel as well as some smaller issues like a broken speedometer and speakers. It just doesn't make much sense to pump all that money into it because even after all those repairs the car itself would still only be worth around $1000.
So my plan is to apply the sealer with the thermostat removed and the heater core bypassed in order to minimize damage, and hope it lasts me into the summer. But if you think I'll get better results by doing nothing at all then I want to hear about it.
Otherwise my question remains: Do some sealers that last longer than others? And I'll add this one too: Do some sealers do less damage than others?
