Thanks for sharing! I wasn't even aware such a thing existed. I'm still in the info gathering phase before I start any demo/restoration work, but as I'm saving information that I know I'll need to refer back to later, this is certainly going to come in handy.
Looking at their website, I didn't see any mention of strength. Any idea how they compare to a bucked rivet? IIRC, I saw a thread where someone mentioned that, regarding the airstream skins and windows etc., the bucked rivets were the strongest connection followed by the Olympic style and then pop rivets.
