Marine Goop is the strongest single component adhesive and is great for multiple marine grade applications. Marine Goop will bond to glass, metal, canvas, wood, vinyl and rope and is ideal for stopping leaks in waders, wet suits, diving masks, rafts, and air mattresses. Marine Goop is also ideal when installing fish finders in your kayak or canoe or.
Good stuff - adheres to plastic, rubber very well. Used on several kayak add-on projects. My gopro handlebar mount snapped from overtightening screws and I used Marine Goop along with some small strips cut from an old credit card as splints. After a 24 hr cure, it's stronger than when it was new.
Used to repair rusted out sections of my car where had to repair large metal hole underneath, used goop and lots of throwaway consumer plexiglass - Excellent results
The Goop was both easy to use and quite effective. My application was using Goop to install D-ring anchoring pads to the inside of my camping canoe to secure both the backrest and serve as the anchoring point for the end of the lines securing camping gear in the canoe. I also used it to fix a pair of my wife's shoes that had the sole come completely off, so Goop is also a versatile product.
It does what is expected and holds wonderfully. Since I was in an awkward position applying it, I had trouble controlling the amount. Also, I squeezed it from the middle (duh) and to no one's surprise it gave me more than I wanted. I was going to recap it and use it again, but I had made too much of a mess to make this doable. I ended up tossing the unused portion since I had made such a mess of it, but would gladly buy it again due to its holding ability. Next time, though, I would be a little better prepared to handle it correctly.
