During my pressurized leak test with soapy water, I found two rivets on the top of the tank (one at each end) that had a very small leak around the rivets. During the soapy water test, they didn't necessarily make bubbles, more like foam....
Here they are
I also had my vent line fitting leak quite a bit and will have to add proseal around it.
With all that being said, Is the syringe method the best way to tackle the two rivets that have very small leaks? It sounds like I need to take the syringe full of pro seak, glue some rubber or rings or washers to the end to help create a seal and then just press the pro seal against the leaking rivet as hard as I can.
Does that about sum up that type of sealing repair? Is there another way to do it without drilling out the rivet?
