FINALLY...just finished resealing the tank. I'm "mostly" happy with the reseal job so far, looks wise I would say passable but not perfect. Since this is my very first reseal though and its so dang big I guess it's not expected to be perfect. There's a few spots where there's some excess silicone that my finger pushed out too far because I did not use any tape. Since every seal in the tank will be covered by the 3D background though none of those spots worry me because they will not be seen anyway.
Far as structural integrity of the reseal job (the important part) I am pretty confident it all went very well. I pushed the new silicone deep into the corners and laid some nice long beads without any spots that look suspect, so I believe it should be a pretty sound job hopefully. We'll find out in about 7-8 days I guess.
Couple pics....
