Aye, I tried fixing my bumper with JB Weld but it eventually gave away for some strange reason. For my second repair attempt I am going to be using both hardware and adheasive, so what kind do you suggest I can pick up?

 

jb weld is strong as hell... the only reason it probably wouldn't work is because it does not bond well to the material you apply it to. try using fiberglass... it works on polyurethane i think.

 

i think jb weld is primarily meant for metal there is a really good glue called gorilla glue i would try that

 

gorilla glue

Its good for small applications though, not really big ones

 

My gosh, any other ideas people?

 

I'm not sure what part of your bumper you cracked or how bad it is...

I was into r/c airplanes for a little while, and had a thing called CA glue. You could put the glue between two pieces of plastic, spray it with quick-set formula, and literally 1 second later it was bonded. It's like super glue, but stronger and sets in a second. One time I had a broken prop (plastic) and no spares, so I glued the prop together using CA glue, and to my and everyone else's surprise, the prop stayed together in flight - where it experiences not only extreme centrifugal forces, but also side forces from dives and climbs. Overall very amazing stuff, you can get CA glue and quick-set at any r/c hobby shop.

 

What exactly is wrong with the bumper?

For my crack i used fiberglass then bondo to smooth it out.

 

JB weld sucks for plastics. I tried it on my cracked abs lip and it just cracks again with ease.
