Superb - best waterproof/outdoor two part glue/filler on the market.
The best glue/filler of its kind, this stuff cures rock solid, with decent work/cure time, and easy to use. Recommend you mix in small quantities, as it sets quickly and becomes lumpy in doing so, if you keep trying to mix it. Superb at its “job”, though, especially for water features (this was a repair to my mother-in-law’s broken water feature, results are perfect!).

does not work on all surfaces, smells awful but does work well on others.
I will explain what i bought it for, how it worked, or not, and what I mean by the smell..... I bought this to fix the loo seat onto the loo and it sort of worked... the loo seat is strange, unlike the usual nut/bolt to hold it onto the loo, it has a hexagonal plastic head with a thin body that goes through the fixing hole and a plastic bottom to stop it pulling through - all one piece. This hexagonal head then slots through a slot on the bottom of the loo seat and has a rubber suction foot which also works to stop the hexagonal head sliding out of the slot on the loo seat. with me so far... OK, SO I tried super gluing and all sorts before resorting to epoxy. having use epoxy before I wanted a waterproof one so that the loo seat could still be cleaned regularly. This product did not stick at all to the rubber foot, which I had decided needed fixing as it had split. This product did not stick at all to the ceramic base of the loo ( glossy surface) it set and popped right off. This product DID stick to the plastic hexagonal head and the inside of the slot on the loo seat ( plastic). so - the loo seat is attached a gain, and if the epoxy holds, I do not need to worry that the rubber foot being split will let the hexagonal head slip out, as it is firmly stuck in place ( for now) I am surprised that it did not stick to the rubber foot, I have used epoxy to stick rubber to glass before and it worked well, perhaps rubber to rubber does not create a good bond? and finally - the smell - oh the smell. Epoxy has always had a chemically smell and sometimes a slightly fishy smell, but this stuff has a really really strong and unpleasant mix of rotten fish and burnt hair - really bad, it took 2 days of having the bathroom windows open to get it out, although it was much less strong the second day, but fair warning - using it indoors is probably not what they had in mind for this stuff and you pay the smelly price for it. I hope this helps.

No good
I’ve had a JB weld products before and they’ve been very good however this is total cr#p. It seems to foam up when drying, it doesn’t set hard and it’s difficult to sand.

I got two packets for an important project. When we opened one, one of the tubes was completely solid. Not to worry, I had an extra one, right? Wrong! That one was also in the same condition. So now we are delayed by a week at least until we get another suitable product, not to mention the financial losses .
