Figure about 30 hours total s o far. Just some final cleaning and then the sealant. On-the-whole, this is about average. The last tank I resealed was in 2007. I only resealed the top half of the rib. The top half of the rib had been re sealed 6 times previously. I dug out a LOT of sealant. I had about 25 hours i n cleaning half a rib. It is a major PITA to clean the tank.
