I am in the process performing the leak test of my RV8 fuel tanks using the Vans balloon method. So how easy it it to detect the leaks using the soapy water? I shined the bright light on the rivet lines but didn't see anything bubbling other than the bubbles created by the spray nozzle. How long should I wait for to check for the balloon deflate, it if deflates as time goes by?
Thanks
