long story, but my IF cracked tonight after some lady in a saturn hit me....
is it fixable or no?
small crack and crack in the big mouth part......
i think urethane is really hard to fix. LIke alot of heat to melt.. i am pretty for sure
or just take it to a shop and have them fix it since the lady hit
you 
for sure. THEY BREAK THEY BUY right?
Get a replacement. No matter how you fix it it will never be 1/2 as strong as it was originally. There are two ways you can do it if you are just fixing it to collect the rest of the money. One way is to fuse it together as some have mentioned. You a plastic welder to melt each side of the crack back together, then to melt some additional plastic on the back to make it stronger and apply a little bit of body-filler to the front. Another way is to reinforce the crack with a thin piece of metal (some people use old liscence plates) and rivet it to the back of the crack, then fiberglass the front of the kit and body-fill it.
I would just buy a new one, it will be worth the little amount of money you could collect from the lady. Just take the car in to get an estimate and let them know its an aftermarket kit and show them the highest priced site online that sells it and they will usually give you that much money to replace it

NEVER USE BONDO OR FIBERGLASS ON A RUBBER BUMPER!!!!!
it is like mixing water and oil it will come off
ok first thing ya need to do is call the insurance company if she hit you then let the insurance take care of this
if not the first thing ya need to do is determin what type of plasctic you are working with, is it a offlien or non-offlien type plastic does the bumper have a code inside it to tell you what type of plastic it is
if no code, here is what ya do take a small piece of the bumper on the inside of it cut a small piece off get a cup of water and try to sink the plastic, if it sinks you can do any type of repair to the plastic , if it floats then you have to use a adheshion promotor before any type of plastic repair is applied to the plastic
take your angle grinder lightly grind both side of the bumper down, then take and put a v-groove in the crack, doin this alows any material to adhere better, yes i would plastic weld using the correct type of plastic rod for the bumper, do this on both sides
on the back side of it i would use panel bond, yes it sticks to plastic let that dry overnight
come back use your D..A. with 80 grit paper sand the outside of it smooth, then apply the correct plastic repair material to the plastic, if you did as i stated above apply the adheshion promoter let it dry for 10 min`s then apply the correct plastic repair material
the drill holes and using rivets thing will only last a few months i have fixed to many bumper from someone else that did that using bondo and fiberglass and i had to redo the entier thing and it came right off with a blow gun!!!
if you have no experience in plastic repair do not attempt doin it your self it is a long process and ya need to know what your doin and what to use on what type of plastic
hope that helped

Judging by his explanation, it was prob a non-reportable accident(under $500 worth of damage) so its not worth taking to insurance since his deductable is prob higher.
But if you do fix it Big Daddy pretty much covered everything.
Ok, dont do what I said, lol. I was wrong.
I have seen a few kits repaired that way and never saw any problems, but obviously big daddys way is the correct way to do it. Never-the-less I dont think it will ever be as strong as it originally was.

First off, dont repair urethane. Get a replacement because Ive NEVER met anyone who could weld urethane back together right(not even the 3m and fusor rep for NC could pull it off successfully with uniweld.) It will eventually break down and show, or leave ghosting. Its a lot better to just replace, which is what most shops will suggest. Second, Big Daddy, in my opion, gave some outdated info. Its okay to use fillers on plastic, let me repair its OKAY. Bondo is a OLD OLD term and its actually a brand not a product. There are plastic fillers designed for the sole application of plastics. During certain situation, and with the right application, a true light weight filler can be applied to plastics with perfect results aslong as its not on a plastic section that flexes extremely a lot(outside corners and the bottom of your front bumper are examples.) Also v-ing(making a v groove) isnt a good ideal especially if you are going to plastic weld. Instead make a u-cut(leaving no stiff hard edges on the panel, everything is contoured.) Reason you do it this way is because when you V something out the edges are really bad stress points and will allow unibond or any other plastic weld to stress and crack especially under contraction and expansion due to weather. When you U something out it allows your material to bond with out unified stress points. Other then that, hes on the money. Sorry Big Daddy, I was knocking you, just thought Id throw my opinion out there. Ive been in the composite/plastics field for years now and these are just simple things Ive learned over the years.
oh and dont buy bondo, period. Buy a nice quality product please.

well you obviuosly don`t work in the collision field , i fix polyurathene tpotpe pp all day long and i have never ever had a car come back when i fix a bumper, actually i just recently fixed a car that i fixed the front end and it was hit again in the front end and MY repair held up to the the impact
everyone has their one way of fixing things i understand that but IT IS NOT OK TO USE A PLASTIC FILLER ON A RUBBER BUMPER!!!! not in any case!!!
the v-groove is what i was taught is what I-CAR teaches as well and to this day i still use it, and it works!!!! 3m products are i think the best in the field, the panle bond is used on mercedes!!! almost every car out there has a 3m product on the car, I-CAR tested the repair on plastic using the v-groove method with panle bond and it held up
yes i do use the new school techniques as well, and the ole skool is the best skool!!!
you do what you want i will continue to fix and build cars my way
the "ole skool" way

Yes I do fix cars, I also hold 3 degrees(engi, mech and a AUB.) Ive seen fillers hold on strong on rubber before but it also depends on how well the repair was done, where the repair is done at and who did it. I wouldnt recommend someone with no experience, knowledge or understanding of products to go buy dynalight and apply it all over his fascia. As for the V-ing out, I heard this from both 3m and Fusor reps(certified by both and some others) theyve been suggesting to u out inside. Its the same thing as ving but you countour the hard lines which reduces stress points in the repair. We all know that the plastic your putting back into the bumper is not the same material so it will swell and contract at different rates then the bumper. Take it as you will, flame if you want, theres not 1 right way to build a car. Those are just points Ive picked up through the years doing what I do. You might not like filler on plastic, thats cool, it can be done though. As far as the u-cut, you should try it and see how well it holds up against a v-cut.

Who 'effin cares! Its getting way to technical. If you want to fix it, take it somewhere that knows what they are doing, proper urethane repair is only for professionals. Sure there are ways that you can do it at home that will probably last a decent amount of time, but nothing is going to be as solid as the original mold, PERIOD. So it all depends on how much money you want to spend and how long you want it to last, I think you can make ur decision from here.
Now stop bitchin!
