Fixes Nearly Anything & Everything! (2010-03-27) Rating: 5/5
I've used JB Weld to repair countless numbers of things over the years... My car's alternator (as pictured), my car's door handle, the broken cover of a USB flash drive, a friend's earring post, broken toys, and various other things around the house & garage... The list goes on and on. I find the two keys to a solid bond to be: (1) roughing up the surface with emery cloth or a wire brush and then (2) cleaning the surface with isopropyl alcohol to remove any remaining dirt or oil left by your hands... Make sure the alcohol will not attack whatever you are trying to clean before using it and make sure the surfaces are completely dry before applying the JB Weld. A trick I learned from a user group forum is that, by using a hair dryer from a slight distance to warm it when applying, the JB Weld will flow for a smooth surface and even coverage. (Just don't melt, burn, overheat, or ignite whatever you're trying to repair by getting it too hot with the hair dryer!) In my experience, heating it slightly has not resulted in any loss of strength once cured. JB Weld may run after applying so I recommend checking it after several minutes or an hour to make sure that it has not run onto a surface where you don't want it. Additionally, it's a good idea to brace, tape, clamp, or otherwise immobilize whatever you are bonding together and leave it that way for the full 24 hours until it is completely cured. This is a great product!... Just be patient and don't apply stress to a joint until 24 hours have passed.

05/06/2010 Edit: Although I haven't had problems in the past using isopropyl alcohol to clean my bonding surfaces, prior to applying J-B Weld products, it is worth noting that the J-B Weld FAQ recommends NOT using alcohol because of it leaving a "petroleum residue". They recommend cleaning with acetone or lacquer thinner instead.
Don't scrap it...JB Weld it is right! (2010-03-22) Rating: 5/5
I have a house built in 1905 with metal box gutters. Very expensive to replace but not repair with JB Weld. I had small rust holes and some larger gaps as well as cracks at the original welded joints that I wire brushed, cleaned with acetone then simply mixed the JB Weld, smeared it on and let it set-up then coated over everything with a little asphalt roof cement. Box gutters are a maintenance nightmare but the aesthetic appearance is no match for the era of my home. JB Weld has undoubtedly saved me hundreds if not thousands in repairs.
Works on Toilets (2010-01-09) Rating: 4/5
I had a very small drip in the bottom of my toilet and I noticed a small crack around one of the bolts. After reading several how-to reviews on different websites, I decided to give this a shot before tossing the toilet. So far, so good! The epoxy was very easy to mix and relatively easy to apply. I let it dry for a day before sanding it down and now there's no more leak on that bolt.
Works very well...give it time to harden (2010-01-03) Rating: 5/5
Directions indicate 15 hours dry time, but maybe that is with an exact mix of materials. I just squeeze out what is 'about' half and half and then mix. At 15 hours, JB Weld still seems a bit pliable sometimes. 24 hours and it is always rock hard. Have a little patience.
