After I sealed the right fuel tank yesterday I had left it overnight for the sealant to cure so today I hooked up a water U-tube and applied pressure to the tank to 1 psid. After just over an hour I returned to find the water level in the U-tube down a fair amount. I made some soapy water and squirted it on the sealed parts. I found two fuel tank panel retaining screws with soap bubbles. I removed the sealant, depressurized the tank, mixed and applied more sealant and will try the test again tomorrow.
