Place the fuel line over the cleaned weeping rivet and place the syringe over that. Squeeze the down on the syringe plunger as hard as you can. The fuel line will bulge out and you can squeeze pro seal in. Carefully wipe clean and do the next one. Simple and no tank removal needed. I was lucky to do mine to an unpainted fuel tank.
No further leaks
This is good information. I too have several rivets weeping on the underside of the left tank. I?m considering this procedure but I?m a little hesitant as I?m not the builder and have never used pro seal.
Do you have a picture of the syringe and fuel line applicator? Do I need to mix the pro seal, or does it come in a package ready to use?How long after squeezing the plunger do you wait to wipe the excess around the rivet? Does the tank need to be empty? How long should you wait before filling the tank? Can you use this method on a painted aircraft? If so, what are things to watch for and to be aware of?
I appreciate any information.
