Shot1,
Attached is a picture of my Compadre and Bandido II µMax faceplates. My wife took the picture, as I held the tip-end of fingernail files very carefully at the juncture of the faceplate arc area and the brown housing. I could see the electrical wires inside the Compadre control box even before I allowed the file tip to slowly slide inside the housing for emphasis.
On the other hand, the Bandido II µMax faceplate was tight against the housing all the way around and the file tip did not go inside the control box one tiny bit !
I agree with dirtykneese, "it is NOT a ventalization spot. It is a defect. You need to call Tesoro and let them know. They will make it right with you."
If you're not satisfied with using silicone, I imagine Tesoro will say to leave the coil cord attached to the control box and coil, as I believe it is hard-wired inside. Then package and ship the coil, cord and control box (Keep the coil bolt and wing-nut home so it doesn't get lost.). But by all means, call Tesoro before you do anything. Talk with Rusty if he's available.
Good Luck,
