[quote=dmgbear55]If a 40 year old mast can be pristine, then maybe. This is all part of the This End Up rebuild. The mast was sanded, coated with an Awlgrip Wash Coat, then 3 coats of Awlgrip 545 (most of which gets sanded off), then 3+ coats of Awlgrip 2000 Jet Gray (that was a bit...h).
For pulling anything but aluminum rivets you need one of these type tools, or maybe a pneumatic tool:

Interestingly enough this thing was no more expensive than a good standard riveter on ebay.
Even if you used a solid rivet I suspect that some number of times the the rivet would not seal the hole. The bulge created by the mandrel does not always create a perfectly symmetrical bulge before it breaks off. Some other step like you are taking is required in my opinion to seal [b]any[/b] kind of rivet. I think threaded screws would be better, but again something is then needed to keep the stainless screw from galvanically corroding the aluminum.
We also need an engineer to step up and tell us the math on how much more righting weight is required for every once put into the end of a mast, for a given mast length and for say an ounce of water or material.
You can see more of the images on my 5.2 project in the Technical Albums on the Rebuild of This End Up.
