Glue for front bumper

Just noticed that my 2000 Caravan's front bumper have cracked. Possibly from
hitting a curb.
I've tried applying "Grazy Glue" but it didn't hold.
Does anyone know what I can use?

Thanks

 

Try Elmers "Ultimate Glue" (polyurethane). It's waterproof. Warning: It
expands and will slowly "squirt out" as it cures so use caution it doesn't
get where you don't want it. Use it sparingly and you may need to check it
occasionally and scrape off the excess.

 

Jimhigh66,
Thanks for the quick reply. Last resort I may give this Ultimate Glue a try.

I'm thinking along the line of modelling kit glue where the glue will melt
the material and create a bond.
Guess the bumper is made of different polymer compound.

 

Sounds like it might be very similar to "Gorilla Glue" that you see in
all the hardware stores - has the same problem of greatly expanding when
it cures, but it is *tough*.

Nope. That works on thermoplastic like ABS. Your bumper is not ABS, and
there is no solvent-type ("melt it together") glue for it.

 

Two brands of the same kind of glue, yes.

 

DuPont and Devoe makes a two part glue epically for plastics and composites
it is industrial only you can get it fron Grainger or McMaster-Carr.

This might be the same stuff that I keep on hand and that is in every
auto parts store.

On the "glues and goops" aisle, there is a two-part epoxy in the (IIRC)
Versachem brand - the packaging has a pinkish-purplish color to it, and
the name on it is "Plastic Welding System". I can tell you that it is
not just regular epoxy repackaged. It is very different - has a very
strong and distinct odor as it cures (rather quickly I might add), and
it really does work on plastic. It is *extremely* tough. You have to
try it to believe how good it is bonding- and toughness-wise. I keep it
on the shelf all the time - it is amazing. Every bit as good as the
gorilla glue without the expansion problem - so it is much easier to
make a cleaner-looking finished job.

Yes, there are several brands and it really stinks. My wife had some one
back into her cracking her front bumper. I drilled a hole at the end of the
crack about 6 inches long. Used denature alchol and 400 grit sand paper.
Glued it and put a wide patch on the back, sanded, primed and painted. You
can't tell it was there that was 4 years ago.

Thank you all for your input.
I did some googling and finds the following links quite helpful.
Will attempt to do repairs when weather warms up a bit.
Thanks again.
