With the trench in the gasket deepened, I began gluing.

I used simple black RTV, silicone gasket stuff that I got at the auto parts store to do the trick. I started with the section nearest the hinges, glueing about 1/3 of the total length. I then closed the trunk lid to hold the gasket while the RTV dried over night.

Here is one thing to watch out for:

I was a little too aggressive in stretching the gasket into place. As a result, the gasket pulled away from one of the corners during drying.

To fix this, I had to pull up about an 18" section, pull everything back into place, and reglue. I used several sections of black electrical tape to hold things down, in addition to the trunk being closed. That seemed to do the trick. If I were to do this again, I would have done that from the start.
