this is an issue i've been looking to figure out myself, only i'm looking to patch a 5 inch by 3 inch hole heh, missing in my bumper. for a small hairline crack, granted you can do this in a warm garage, use a fiberglass cloth with at least an inch or two overlay in all directions around crack and some plastic weld appoxy on the back end of the crack on the bumper, using several layers of appoxy and a couple tubes of appoxy... depending on how big the crack is. suggest mixing in an individual metal dish or tin pan for each coat you're putting on, allowing at least 3 hours to set or as per instructions, and apply with popsickle sticks and paint brush. then on the outside, i would imagine any kind of body filler (redneck bondo, haha) to fill the crack and small sanding around the crack area with some touch up paint, or if bad enough, a full bumper paint if you aren't pleased with the look of the job. depending on brand and strength, appoxy can be strength assured anywhere from -40 farenheit to 180 fareneit... it's very reliable.

edit: appoxy can assure bond and prevent further spreading of a crack (experienced in patched radiator repair cause you're too damn broke to get a new one: 101!!! )

but i used a steel puddy but im not sure if it would be good or not , would appoxy be flexible tho?

appoxy is very strong, flexible, but not solid like a piece of metal would be. appoxy is good for strengthening plastics and with fiberglass cloth, will be close to twice as strong as the rest of the bumper... at least in that one little patch. i forgot, and it's almost as important as using the cloth with the appoxy, CLEAN the hell out of the area under the crack first. i would assume that any body filler on the outside of the crack would be sufficient. i don't know that much, so it would be smart just to pick up some appoxy tubes (or how much you need) mix the two chemicals in the tube... using about half of the thing into a bowl with a popsicle stick...

you can go about this two ways:
1: put a little in the corners of the crack, apply the cloth and put appoxy over it.
2: put the cloth in the appoxy to fully soak it and stick it on using a small paint brush.

get some appoxy if you can that is formulated to be applied in cold weather (if they make it i'm guessing they would) cause i think it has to be over a certain temperature. and as far as the hold times or setting times, they sell a 5 minute, 10 minute and 15 minute appoxy... well, basically, the longer the initial hold cure, the stronger your final bond will be when the appoxy has fully cured

trust me, appoxy would definately be the way to go to ensure a PERFECT bond and again, the appoxy patch should only be used under the bumper, lol, looks like a nasty yellow color any how
