I'm looking for a puddy type material to use to seal where my ignition wires come out of the cases.  Any recommendations?  I have been using silicone, but now looking for something more solid.

Try some marine bedding compounds/sealer. Sitka Flex would be my first choice if it is still around. Mask off what you don't want to be covered. While in the marine industry this stuff had to cut off with a razor blade to be removed.

   How ever you seal the wire exit pot and grommet, make sure the ignition case is vented sufficiently up under the tank  or seat. This helps more than sealing any suspected leaks. A nice hot engine hits a cold creek crossing and the air inside the case contracts and will suck water past the best fitting case cover and sealing job. It used to really mystify me back in the day until I was clued in on it. I would always get some water out of the ignition case post race no matter huow well I thought it was sealed. After venting with a standard compression fitting and plastic tub run up under the tank, it was always dry after a race..

Good reminder about venting.
I've used this in both auto and moto applications-does better than silicone seal:

Wow! I learned something new today!  Thanks Dan.  Yes my case has the original fitting in the case vented up under the tank.

I use this too.  Didn't think it would work on the gaps going into the case...
