More useful than I thought.
I have a small water leak into my Land Rover. I knew where it was coming from seam and it was proving to be a problem. A friend told me about Captain Tolleys years ago. I was pleased to see that it was still available. So, the only thing to decide was whether to go for the small bottle or the big one. I am so glad that I opted to buy the Bigger bottle. Since buying it, I have used it on numerous items for sealing. It's a great product and works well. I like the fact that as a liquid form it's white colour and therefore easy to see but then goes transparent upon drying. What could be better?

Easy to use and extraordinarily effective.
Very effective. Used to fix common leak on Ford Focus estate roof- which can be a big job. Likewise sealed a screen leak that I'd put up with on an older vehicle for years. It does flow very freely so be aware and ready to mop up the excess.

Ingenious product, badly designed package
This stuff is brilliant, it's packaged very badly. First the good, if you've got a tiny leak somewhere or a pipe leaking at a thread, drip this stuff in and it's gone, heals small cracks in vessels quickly and easily, it creeps into the cracks that cause the leak and seals them in a few minutes. The negative is how it's packaged, you have to pierce (not cut) the top of the bottle. However, the style of the top lends itself to being cut so we cut it, then had to reseal it by melting it back together, and then putting a pin prick in the top of it again! After opening, the lid doesn't seal it properly (ironically) - even when you open it properly with a pin prick - so if it's not stored vertically it either leaks or seals the lid to itself!

Established product in a large quantity and good price
Good value for bottle size. Does work eventually after a few applications. This is normal as it's very thin. Let it dry and go again until it doesn't sleep away and then the leak is fixed. A necessity on the boat. With such a large bottle (it goes a long way), it's worth just going around deck fittings for the sake of it in case there is a lead. Saves having rotten core etc.

An amazing product
I used this to repair a concrete fountain reservoir which had suffered numerous fine cracks due to hard frosts over the last winter. I'd already made various attempts with epoxy resins but nothing worked and I'd resigned myself to scrapping the fountain when I came across Captain Tolley on the web. It worked brilliantly - I applied the sealer to the cracks and it immediately penetrated deep inside them. I reapplied until it stopped disappearing into the cracks and then left overnight.On filling the fountain next morning there was no sign of leakage anywhere. That was several weeks ago, and there has been no leakage whatsoever. BRILLIANT! I've got loads left for any future repairs, so it was well worth its cost.

I have a non leaky Landy!!
So, I was vexed with the Land Rover curse of being unable to find the hidden leak on my Land Rover Defender roof. Bought this to try in an attempt to stop water finding its way in. Tips : don’t cut the tip off, just a very small pin hole. This stuff is watery. Make sure you have a cloth to wipe up excess. It dries clear which is great as my roof is black and leaves no sign that it’s there! Which is great. This stuff literally flows uphill so I’ve done my window seals also! First rain, NO LEAKS!! RESULT!!!

What nobody tells you!
I suppose this stuff works, well I hope it does! However I found it went every where not just over the hairline crack and its very runny. But please ensure you do not spill any on the perspex windows and it will melt into them. Leaving them with a big ugly mark on them!!

Seals hidden and hard to find leaks.
Needed this to seal a leak on the boat. It was a little tricky to open since you only need a tiny hole. Once opened its very thin and easy to apply. It seems to have sealed the leak so perfect

VERY EFFECTIVE
I have been using this product for more than 10 years on my boat. It is great for filling in very small hairline cracks that cause water to leak through the deck. You need to apply it at least two or three times, but it is very effective.

Magique
Plus liquide que de l'eau ? C'est vrai. Je l'ai utilisé pour remplir des microfissures d'un plateau de douche. C'est simple à utiliser et efficace

Fancy name and price for something pretty common? Works as it should though.
Very low viscosity wich can be both good and bad. Seals thin gaps but wont fill anything. The product itself looks and feels like the stuff commonly used as moisture sealer under tiles etc. that you buy for a fraction in the home improvement market.

Non funzionante
applicato su crepe inveriori al mm Asciuga con tantissima difficoltà, asciuga facendo grumi e non riempie le crepe Tra l'altro rimane trasparente ma quando bagnato dalla pioggia ritorna bianco come se non fosse catalizzato bene e assorbisse ancora acqua

Panoramadach wieder Dicht
Es ist eigentlich sehr traurig das VW sich weigert das die eingebaute Panoramadächer von Werk aus ein Produktionfehler ist. Habe ein 2018 er VW Sharan, natürlich denkt man sich nichts böses und göhnt sich mal mit ein Vollaustattung also auch mit Panoramadach. Letztens bei Starkregen hab ich bemerkt das A Säule auf einmal feucht und Nass ist. Hab natürlich als erstes auf Abläufe tippt, das sie verstopft sein könnten obwohl ich alle halbe Jahr alles durchgehe. Sie waren beide nicht verstopft. Mittlerweile ist man ja nicht blöd und googelt raus ob es doch ein bekannte Mängel ist. Tatsächlich ein Volltreffer. Einige Forum beiträge durchgelesen und bin dann auf das Produkt Captain Tolley gekommen. Hab mir natürlich denkt bevor ich die liebe Werkstatt besuche Probiere ich mal das Mittel und gleich 250 ml Bestellt. Nach ein gründliche reinigung mit Bremsenreiniger habe das mittel mit mehrfache Verwendung eingesetzt. Man braucht eine Spritze mit langem Nadel, vorsichtig auf die Stelle wo Kunstoff und Metall sich treffen rauf gespritzt. Ca. 2 stunden Trocknen lassen , dann das ganze noch mal wiederholen bis man merkt das das mittel einfach nicht mehr rein geht sondern oberflächlich stehen bleibt. Danach einfach 24 stunden trocknen lassen. Vorsichtig die Abläufe natürlich mit Lumpen zu decken. Es sollte dann bis zu 2-3 Jahre heben dann einfach das ganze Wiederholen😉. Habe auch 2 Fotos Hochgeladen wo man die undichte stelle sehen kann. Lg
