The round tunnel is a good point but I think from a financial perspective I'll have to live with that.

Let me tell you about the time I had to reach for my under dash e- brake...
True story I tell you!!
Tebs
almost as long as a Stan Galat story
...but somehow the content can't stand up to Stan's...
1. Rear disc brakes
2. Espar Heater
3. Built with truck bed sealer + Dynamat
4. 2,000 + cc's
In order: Safety, comfort, performance and only then, whatever else you want in your car.
"truck bed sealer" ?
Yup, Truck Bed Sealer.
I would put the body onto the pan using several tubes of Contractor-sized silicon caulk, let it set up for a few days and then spray the Bejeezuz out of everything under the car with rubberized truck bed sealer, wait a day and hit it again. THAT would make it waterproof, at least from below. I may even re-do mine this Spring, if I can get it onto a lift. Power wash it one week, hit it with sealer the next.
Jack has the right idea, for sure. Even if he lives in 40'th-ranked Arkansas. (At least it's really pretty there.... And I don't get to tell people our taxes are less than theirs very often!)
Where I live rubberized undercoating is a thing of the past unless used in rock prone areas as the rust just gets underneath secretly 
They used Waxoyl Cavity wax a lot or Krown in the seams after POR15 treatment from fresh.

None of you guys got this?... that was a poke at Tom from his Leno episode. "Let's take a look up front..."
Nobody?... sheesh... tough crowd.

I did this same process when I built Eleanor.
The underside got two full coast of truck bed sealer/liner after a round of silicon in all the joints. Top side got covered in peel n' seal (like dynomat). Top side also got a round of silicon in all the joints.
Once the body was installed, I did another two rounds of silicon in ALL the contact areas for the body and pan. I also used the same sound deadening materials in the inside body...
I still have a few more spots to do, but this thing is going to be solid when I'm done!
I personally don't like silicone .... seam sealer like the manu use is more to my liking as it remains flexible
I should clarify...
This is the stuff I used around the seam where the body was attached to the pan.

This is what was recommended to me to use...
