What a great product name! Some time back when I was researching how to seal the 109
bucked rivets on our Pete's roof I found a couple of threads mentioning this product, but none titled as above. So for easy searching, here is my report.
I just spent 3 hours over two lovely central Florida afternoons (sorry, I had to) cleaning and sealing around the like 109 rivets on the roof of Pete. Just like Captain Tolleys says, clean the surface, apply the product, and re-coat in 30 minute intervals. Since our coach is still pretty new (a 2014 27FB delivered in Nov '13), I figured 2 coats would be enough. It only took moving and going up/down the stepladder 36 times.
Why did I do it? Am I crazy? Bucked rivets don't leak! Well, coming from a tpo/rubber roof RV world, I know that anywhere water stands on the roof can be a leak. That's why many tpo/rubber-roofed rvs have bulges in the sides and soft interior walls. The water gets stuck in the roof corners due to poorly designed drainage (read none) and it has to go somewhere, oftentimes finding it's way into the wall.
As I admired our Airstreams wonderfully curved roof, I noticed early on that there are all these rivet dimples that can/could/do hold water when it rains. As we use our coach quite a bit, it gets wet when we camp and it's not in it's barn. Hmm........ What to do. Captain Tolleys at least helps me feel better about water sitting in those dimples. If this stuff wicks in say 5% of those rivets, maybe water could have, so why not? I figured if the dimple had dirt in it, it had water in it right? And yes, anal-retentive needs a hyphen.
The pictures explain how it looks before, going on, and ending up. Carry on fellow Airstreamers.
