    Once you have the bumper off you could repair from the back.

    If you can get a pic up you will get a better responce

    I think you might be able to patch it on the back side.
    You might need to slash the inside face a few times with a stanley knife to give the fibreglass something to bite onto, wet the sides with the resin, lay on a sheet of FG, and soak it with resin again.

    Wait for half an hour or so til it goes off (don't mix too much resin, as that will have gone off too)
    And shove another sheet on, resin it again.
    2-3 layers should do the trick, but make sure the crack is set right, so you don't glue it together out of line.
    You'll still need to tidy the front face, and it can crack there again, as it'll be a point where everything around it flexes, but the join would crack, so be careful!

    Looking at your bumper I am thinking of clamping where poss and using isopon p40 fibre glass on the back to hold it together.

    As stated in other post score to provide a good key.

    Would be interested to see what others suggest

    when rubbing down the paint dont use to higher grade wet and dry otherwise you will swade affect the plastic id use 700 wet and dry and a epoxy glue works wonders for adding strengh to cracks.

    Have you got an electric soldering iron?

    This is the best way to repair plastic bumpers, trust me I did mine

    Also, browse youtube using "plastic welding" as your search title

    I repaired mined from the back and then the front and sanded it back so that a touch of filler and primer could be added before it was sprayed
