Stay afloat don't sink

Silicone is a bit sketch. The sun will eventually destroy it, and I think it's a bit questionable below the waterline. The only good thing about it is it's easy to get off. You should use a sealant specifically made for underwater use here, such as something polyurethane based.

This is below the water line and needs to be done annually. I would rather have 4200 however the Biden administration has left us without.
