Good Product
I like this product for several reasons. It dries to an off-white color that is almost an exact duplicate of the boats gel coat. The product dries relatively quickly, leaving a hard finish that can be sanded. The only real complaint I have is that it’s sag when placed on a vertical surface.

Did the trick!
It wasn't as easy as it sounded to get the two sides prepped evenly for dispensing (bubbles remained on both sides). Once I got close enough, it was easy enough to mix up and apply. The overflow cylinder in my toilet above the flapper had become detached at the base and nothing I tried until this solved the problem. It took a little longer than 24 hrs to cure, (maybe 36)? But once it did, it's held fast ever since and my toilet tank will fill and I can flush again. So glad I tried it!

Excellent epoxy for submerged applications
Used it to seal a resin garden fountain with a cracked water bowl. Over 2 months in so far and absolutely no leak. Not the easiest product to apply but its thickness kept it where it was applied which for a bowl shape is a bonus. Very impressed.

Permatex works, but slowly
Repaired Resin Statute. Pros: covered cracks well; seems waterproof. Cons: took a week to dry & still felt sticky; area turned ugly brown. Have several lion statues that need repairing. Will try using on them as well.

Fixed my fallen pool tile
Had a couple pool tiles come unseated over the course of normal use. I was able to use this product and so far so good with the repair. Bonded well and seems to be holding up a week later, hoping that continues through the summer. Fairly easy to apply, I just wish the mixing stick included was a bit more substantial, I needed to use a popsicle stick to properly mix and apply. Other than that seems to do what it describes.

Works as stated.
Had a leak in our RV sewer line while we were on vacation and needed a quick fix until we got home. This fixed it super quick and held amazingly well. Will definitely recommend.

Never cured for me.
Love Permetex products, however this one never properly cured for me, I was trying to replace a fin on a paddle board and this just stayed wet, never hardening. It was properly mixed…will try something else. First time one of their products didn’t work for me, bad batch?

Works great!
Was looking for waterproof epoxy, to stop a very small toilet leak. Tried this, Used on hairline crack on bottom of toilet not the toilet bowl or back of toilet but the very bottom part of the toilet where the water travels down the hole when u flush it. On the outside there was a hairline crack and we put this on there and it stopped the leak. Dries in 24hrs, took a while bc the surface was wet, its hard to get the water out of that part of the toilet so it kept leaking while trying to put on the glue, lol.

Pega fuerte y resiste el contacto con el agua
Lo use para pegar un niple de acero inoxidable en una válvula plástica de polipropileno, quedó muy bien.

Buen producto
Buen pegamento pero hace falta que una ve que lo usas quede con cierre hermético para volver a usarlo, ya que seca muy rápido y se desaprovecha mucho
