That is the game plan I am stripping all the old silicone and re-sealing the entire tank. Some of the old silicone looked like it was about ready to start leaking anyways. All in all not too bad of a process. I estimate by the time I am done I will have 12-16 hours into the stripping, cleaning and re sealing process.I would reseal the entire tank just in case. It'll be time consuming, but if it had one leak it can have another, soon.............
