I have a small coolant leak, I think its coming from behind the water pump. I probably didn't clean off the old gasket before i put the new water pump on. But i'm going on a trip and don't have time to fix the leak.
Would it be ok to use the Bar's Leak stuff for temporary fix?

One time I threw about a half teaspoon of some ground pepper in the radiator of one of my old dirt bikes. It stopped the leak for the most part in a couple bashed up tweaked up radiators on my old cr500. Don't know if it would help you.
It might stop the leak, but then again it might not. It will probably clog the lower portions of the (block's) water jacket, which will cause the engine to run hotter and may prevent you from using a block heater should you want/need one. Later (much later), it will flake and circulate through your cooling system, plugging passages.
I keep a single tube of AlumaSeal for emergency use only, and if I'm forced to use it I follow up with a proper repair just as soon as possible and an overkill cooling system flush which I repeat a few months later. It can make the repair more difficult by hiding the leak, and it will shorten the lifespan of the water pump.
You'd be much, much better off just taking a few hours to fix the problem before your trip. It might be a royal PITA but it'd make a lot more sense.
My old neighbor had good luck with a leaking radiator using that stuff, but like the above have said I wouldn't use it. I saw that years ago. Someone used it on my old mustang at one point. Found out when I swap'd the water pump and thermostat out. The thermostat housing was half clogged with buildup from that junk, and there was buildup in the water pump fins itself.
Last fall I threw a bottle of Bars into my Camaro hoping to plug the heater core up enough to give me heat for the winter. It held fine until the first time I got on the throttle, then I was back to a puddle of coolant on the passenger side foot area. I ended up replacing the heater core but I didn't flush the Bars out. Big mistake.
When I pulled the engine out this winter EVERYTHING was coated with that crap. The intake, inside the block and heads, the hoses, water pump, etc. I would never use it unless it's for a few hundred dollar beater.
