Resealing
first, if you can, always get the tank low and away from any walls to re seal.
This isn’t the first time I have resealed a tank, but I have not done it often. I taped all around and put me bead of silicone down. Next I pealed my tape. I went to get some fresh air and came back 15ish minutes later to find that edges of my bead curled up. I am guessing I should have pulled the tape as I went. I didn’t trust the seal with the curled edge. So… I scrapped it all off, and scrubbed and scrubbed as much of the residue off.
I reapplied and without tape and it worked much better.
