I have also tried sealing remotes with silicone and found was an issue in the switches and battery, so your method must be better.
Is it really submersible? I don't think you can replace the battery. I have a design that uses 2xaaa batteries and it boosts to 12 volt to get the best range still, I'm working on making it waterproof and with those batteries it can last a very long time.
I opened one of the remote controls after an immersion test of more than an hour.
I could see that the Loctite SI5398 cured well after closing the case without engaging between the keys and the PCB. There is no trace of water in the transparent silicone protection of the keys. I would like to send pictures but I am limited on this post
The downside of AAA batteries is that they can leak acid. On a friend's boat, I had to throw away the Raymarine remote because the AAA batteries had leaked and it was beyond repair when we found out. You need a waterproof assembly with the outside but also with the batteries.
