I used the product to repair the stern of my square back canoe. Worked as advertised with a strong permanent repair. I tried to use it on some leaking rivets, but I had repaired them several years ago with West Systems Aluminum Boat Repair epoxy. When I heated up the rivets the epoxy caught fire, so I decided to seal them again with epoxy. Had I not used the epoxy previously I believe the aluminum brazing rods would have been a better, more permanent repair.
There were problems with the post office losing my original order. When I called to check on it I received courteous and prompt help with a second shipment via priority mail. Tremendous customer service. Highly recommended!
