A bigger challenge to the fangs was filling in the reflector and squirter openings.
Not really more difficult, just a bigger job.
The first step was to cut back some of the plastic behind the openings.
You have have to support across the opening, and you have to provide a good amount of surface area for the epoxy to adhere to.

In this pic you can see how some of the plastic was cut back and also see how the surface is roughed up.
After the plastic was cleaned with acetone & sanded with course paper, the surface was roughed up with a rasp file.

This is the aluminum support mesh laid roughly in place.
This mesh gets embedded in the epoxy.

Similar pic to above showing plastic cut back & mesh for squirter openings.
pic4
This the support mesh bonded in place.
-spread the epoxy on the bumper surface; press the mesh down into the epoxy; then trowel on more epoxy to cover.
pic5
This is the front side showing a donor piece cut to fill the opening.
- NOTE how the edges are feathered back on both the opening and on the bumper fill piece.
I used a half round rasp for this.
This is a really important step in getting a strong bond.

This is the first rough fill coat.
Don't try to be too fancy, just make sure that its worked into that feathered edge joint.
You don't want any trapped air bubbles at this stage.

The second pass.. still some more to fill.
