Bonding nose panel to bumper cover

As the title suggests, for some not terribly vital reasons, I am bonding my 951 GT-Racing nose panel to the bumper cover. Both pieces are gelcoated fiberglass. I tried to sand off the gelcoat to give a fiberglass to fiberglass bond, but there is too much gelcoat, so I am working under the advice that epoxy will mechanically bond to properly prepped gelcoat. I'm using West System products.

Here's the plan. Tell me where I am screwing up:

1. Sanded the areas to be bonded with 40 grit sand paper
2. Drilled holes in each piece to allow the epoxy to seep through and bond better
3. Clean area with acetone
4. Lay epoxy down on each piece, join the pieces and clamp/screw them in place
5. For extra strength, using fiberglass to reinforce the back side seam of the now joined unit and build up the areas that flex. I may then rivet the joint too, but I think this is overkill
6. Finish off with filler, sand, prime, paint.

This is my first time working with fiberglass, so if anyone's got some tips out there, I'd appreciate it!
