Did I mention I hate working with pro seal? All steps followed per the plans. Air leak test worked great. Sat for 2 days with no noticeable change and then test was repeated again. After wings were installed, the tank was unsealed and re-cleaned with gas. I painted the fuel vents "red" below the wing because it will definitely cause an oowie for anyone that accidentally hits it with their head. Calibration of the fuel quantity with the G3X went well. I did the first five gallons at one gallon intervals and the remainder at 5 gallon intervals. The fuel caps were powder coated red but I may buy polished aluminum ones in the future.
