Part 3 - Watertight container (continued)


To make the seal for the WTC lid, I used:
  • Clear, RTV Silicone Adhesive Sealant (66B) made by Permatex
  • masking tape
  • clear plastic wrap
Using the masking tape first, I taped the inside and outside lines of the seal on the underside of the lid. If you look real close, you´ll notice the seal will be inside of the wing nut holes. By doing this, I won´t have to seal each one of the studs.

I ran a bead of silicone for the seal, turned the lid over and placed it onto the clear plastic wrap. This enable me to set the height of, and flatten the seal.

Finally, I stepped back to snap some pics, patted myself on the back for a job well done and made sure my wife and dog would not interrupt the drying process.
After drying overnight, it was time to remove the lid from the clear plastic wrap. To my surprise, the seal was still not dry. I guess it was because air had not been able to reach the seal. Anyway, I let it dry for several more hours during the day.
Next ... it was time to test the seal. I secured the lid with the wing nuts, filled up the sink and placed a weight on top. There it sat underwater all night long until the next morning.
Look mom ... no leaks. Sure, it wasn´t ten feet underwater, and the pressure was minimal, but the first test was successful. Future tests (without the electronics) will be conducted at the bottom of the swimming pool when the weather warms up a bit.
