I’d also like to know this. I book marked this product years ago as it seems like a useful product.

Used it for temporary fix on boats - can work well if there's not too much movement, and its a small crack/pinhole. Its a very thin runny liquid (think of meths for eg) that creeps into the crack and then thickens/hardens, sometimes needs a few doses to build up enough of the hardened material before no more will seep in. It would be difficult over a large area I think. as cyberyacht says the residue can be messy if not cleaned off before it hardens (surprisingly quickly)

Do you think it would be any good for sealing a hairline crack in a domestic ceramic shower tray?

Used it to do a crack in a epoxy/cement type bird bath, worked well and lasted 6 months until the frost came along which was the reason for the crack in the first place. It might give you some time, but if there is movement in the tray/crack......

it would do as a 'quick fix' or emergency repair until you could do the job properly by removing old sealant and reapplying .. but personally I wouldn't use as it may hinder that process

I used it in both sailing and motorhome situations.

We had an intermittent leak from the front windscreen in our A class, not huge but enough to worry about.

We were in France when it was quite warm 2 or 3 applications and no more leaks and that was about 4 years ago. I think making sure things are dry is key.

Oh I see some people are being more detailed in their answers so I'l better join in...

I've used it with great effect and no problems numerous times. Mostly on perished or otherwise less than perfectly functioning rubber seals around windows.
Mainly on old cars but most recently on our old Ducato. We had leaks around the windscreen, drawing on my previous experience I pushed the Tolley's nozzle under the edge of the rubber where I could lift it enough and just let the stuff run freely.
Then all around all eight sides (against glass and metalwork, 4 sides each - bottom was more tricky but managed to squirt it) and all over all the exposed rubber. Not all at once, just the easy & obvious seams bit by bit until the rain stopped coming in. Then covering the whole exposed rubber was for bonus.

Got several years dry travelling until drips of rain started to find their way to my right foot. I knew there was a little area of former bodywork where the metal had made its way to the happy hunting ground but just didn't warrant replacing so, more in hope than faith (foolish me) I just poured some Tolly's into the hole. Probably some of you will say I should have done something more sensible but you did read the bit where I said old Ducato...

Anyway, the rain stopped coming in, the cost to me was zero (already bought the stuff!!) and it gave us another 4 yrs dry-foot-driving before we sold the vehicle in favour of one with automatic transmission. (Gave the new owner her own bottle of Tolley's.)

So that's why love the stuff 🙂🙂

Edit:
O I just read the question properly!! Sorry not used it in that specific setting but don't think there's anything to lose by trying it. It's very watery, almost like slightly diluted milk, but it does what it says on the tin (bottle) - it creeps!!
Just be careful to catch & wipe any wayward runs. Add more tomorrow. And the day after etc until no more goes in.

If it doesn't work & you need to do something more invasive I don't agree that it would make a 'proper' repair more difficult, it's just very thin but quite solid once dry.

Thank you, that is what I needed to hear. If the area needs to be perfectly dry, I have no chance, it`s always soaking, removed the aluminium strip, took off both old rubber seals, and have been taking hours to clean off all the old [ 27 year old ] gunk from the strip, when perfectly clean, I have new rubber seals for both edges, non setting mastic strip for in between, and new stainless screws, and plastic infill strip, also Sikaflex 522 for the screws and heads after tightening. Thank you all for your input.

It can leave a mark if you don't wipe the surplus away. Only used it on yachts though.

It'll take paint off if you don’t watch it and mop up the excess as it creeps out - it sealed the leak in my old VW T25, but at the expense of damaging the paint 😂

Yes, that's what I used it for.
Oh. Sorry, not ceramic, but plastic in a caravan.
Worked very well. But need to build up several layers, allowing each to dry before applying another.

Wouldn't be without it, used it on numerous boats for window seapage and it just worked. If the gap is hairline it will fill it very effectively. Well worth the space in your toolbox.

Ive sucessfully used it in car brake light clusters (two cars). One i had to drill small hole in bottom to drain the water out and when all totaly dry filled with epoxy the cracks filled with captain tollys. more than one application. As mentioned wipe off excess.

Used it on boats, it’s for fine cracks only, needs good weather as you feed it into the crack using capillary action and when that dries you feed some more in, and so on until it fills the crack. So would say it’s not suitable for a rail.

I doubt it would be a permanent fix but, I used Capt. Tolley’s on my first yacht. It cured a leak on the toe-rail, and another on the ‘awning rail’ style fitting for the cockpit canopy…

I used it on a side-wall leak on my first moho, as said earlier, use it once, wait a few days and apply again.
Worked brilliantly on what was quite a big leak.

I don't a 737, but, my brother in law said the local baker had a radiator leak and put dough in Radiator on his Bradford van ( just showing my age),to cure leak , eventually the brother in law changed radiator, but it was so heavy it took 2 to lift it, 😄

Yes. I found it really useful on a roof joint where there was a small leak. Great for hairline cracks especially if you are not sure exactly where the leak is coming from but you know roughly where. It is so thin but sets quickly once in the crack.
