Second Tank Finished and Leak Free

I have been steadily working on the plane but time has been a little harder to come by and given a choice, I'd rather build than blog. Below, I've finished the second tank and I just need to wait to let it dry before leak testing. This tank went much faster and using the Semco sealant gun made it much easier. The first tank took about 3 months to finish and the second tank took about 3 weeks! The wood cradles on top of the tanks are only there as a place to store them. Update: The tank tests leak free! I went through 2 bottles of soapy water going over the pressurized tank three times and no leaks were found.
