Was a little concerned about my max silicon thickness 3/8 on the bottom, but according to research its all a matter of time and temperature. One time table says the average cure rate for 1/2" thickness is 3 days while 1/8 inch is 24 hours.
Its hard to believe I used 80 ounces of silicone sealant, 75% of which ended up in the trash. One thing for sure GE silicone I at $4 a tube is allot more reasonable then aquarium silicone at $9 a tube.
Some of the past thick 1/2" blobs that were squeezed out of the tank bottom before I cut them off after curing took 2 days to get hard. Fine with me as long as the tank doesn't leak or split.
Im wondering if it would be wiser to level the truck on stands (no suspension) and test the tank inside the truck with padded sides so that if a panel catastrophically splits, the glass will land on padding for re-use instead of on the concrete and being destroyed?
While the tank is once again curing I better get started on repairing and refinishing the canopy.
