Gday,
Yes, they can be repaired however, would never be as strong as the original moulding unless your beefed it up conciderably (Recommended) otherwise, hitting a bird at 100k's is sure to ruin your handywork. The weakest point I've found on mine is the 4 circular mounts on each corner.
Also, you forgot to mention the most important grill of all! The BBQ grill! Hehe
Cheers
