I did not try this. Personally, I do not recommand to use this adhesive in a high temperature and vibration environment.
Rubber boots are a natural for Goop. The product itself becomes just like rubber when it dries. It is waterproof and slightly stretchable just like rubber.
No, this will not replace carpet fibers in a rug.
When Goop dries it is somewhat clear...but not crystal clear and it is rubbery which makes able to absorb shock without breaking.
yes, it is nearly the same product but goop has a higher melting point and better adhesion than shoe goo, i've tried to use shoe goo in place of goop before and it doesnt have quite the same hold and it dries less solid/more flexible, i would recommend goop over nearly any other glue product out there, had a microwave handle glued that lasted longer than the microwave it's self, i've used goop to replace sections of plastic that fell off my pocket knife to cover the metal bits and it took months to fall off completely, replaced the glue when it fell off and its still holding to this day, another thing that NO ONE really cares about, goop can also be used to insulate high voltage terminals and prevent arc over as well, i used some on the muffler on my bike to seal any extra gaps and despite the fact some of it melted off, it actually left a leathery plastic coating on the area that could still be pulled off easily enough with pliers when i had to do maintaince on the engine
You may be able to repair the flapper with Goop but you probably won't have much surface area along the thin rubber edge for the glue to hold. If you could cut a narrow strip out of some other durable material you could glue that across the top of the 2 broken parts of the flapper with Goop. If it were me, though, I'd just get a new flapper from Home Depot...They're cheap!
It should hold.
I've found that it works well on glass (not edge to edge ....needs a bead)...The only problem is that it is not UV protected. It will degenerate unless kept out of the sun, or painted. I think Marine Goop is UV protected.
Make sure the treated lumber is dry...you also need to protect the Goop from sunlight. The uv rays will kill it fairly quickly.
