Cracked bumper: Product? Solution? Options

[dudeofchaos]

My bumper is cracked on the edge where it connects to the fender. (See picture below)


Is there anything that I can use to make it hold? I've talked to a body guy and he told me he doesn't know about anything that can make it hold since this bumper is made out of a special plastic that doesn't crack easily but when it does, there's nothing to do with it..
I'm going to sell it eventually so no tie wrap, I need something subtle.

Any ideas?
Thanks!

i use 2 products.

for the inside of the repair, i use lordfusor 142 extreme plastic repair, with fiberglass cloth backing if needed for strength i wouldnt use it in the corner like that, and for the outside, lord fusor 114 (google them for lots more info)
the 142 requires a special gun to despense it, but the 114 dont.
thats how i made this:
