Easy fix for firewall grommet leaks

When I ran all of the wires through the large grommet in the firewall for switches, I didn't know about the way that water can flow over it and leak into the cab (as you can see from the water spots in the picture), So it did. As soon as the the weather warmed back up I grabbed a couple of packets of Sugru and molded it around the hole. After 24 hours it sets to a nice silicon plug and I'm back to being leak free.
You can make your own if you don't want to buy sugru by mixing silicon caulk (not silicon II, pure silicon caulk) and cornstarch called oogoo.

Hope this helps someone
