Sand the aluminum lightly and then clean with 70% isopropanol (let dry), then just cover all the rivets and the seam with the PC-7. You can get a smooth finish by wetting your finger in water and then smoothing the epoxy with your wet finger (redipping finger in water as needed), otherwise the stuff is really sticky!

Simply so, Do rivets leak?

Rivets also won’t loosen once installed because the rivet body is as large or larger than the hole it’s put in. They also won’t shake out or break off, and the tight seal helps prevent leaks and seepage. Blind rivets can compensate for irregular holes, as long as they are within 0.004 in.

What is a blind rivet?

Blind rivets, also commonly referred to as POP Rivets, are mainly used in applications where there is no access to the rear (blind side) of the joint. To use a blind rivet, a hole is drilled then the rivet is seated inside of the hole. Then a tool pulls the mandrel against the hat of the rivet.
