Review: Great job on canvas tents - Easy to use, waterproofed two large old canvas tents effectively with half left in bottle yet! Diluted and sprayed with vacuum pump. Good value, there hasn't been much rain to test true effectiveness this summer but happy with results so far. Plenty left for further applications.
Review: Great product but needed 5x the recommened amount to waterproof my coat - I used this to protect a 3/4 length cotton coat. With my first attempt, following the machine wash instructions, the process failed to waterproof the item. With my second attempt I pre-soaked the coat in a mix of water and the 3 times the recommend amount of product, and then machine washed the coat with another 2 cap fulls of the product. The second attempt was successful and my cotton coat is now waterproof. I would like to give 5 stars, as being able to waterproof something at this price is amazing, but I have to drop 1 star for this problem with the instructions that I encountered.

### ⭐⭐⭐⭐⭐ Great job on canvas tents

### ⭐⭐⭐⭐ Great product but needed 5x the recommened amount to waterproof my coat

### ⭐⭐⭐⭐⭐ Still the best
*by P***B on 21 November 2022*

Most recent use was my heavy old army coat. I got it soaking wet then sprayed this onto it ang hung it by a radiator to dry over night. I've included a video showing how the ancient old heavy canvas coat shrugs off the water. Now out in the rain the top layer of the coat is going to soak up a little rain BUT it doesn't get through and the coat still breathes perfectly well. Also use this stuff on waterproof coats and tents that need a recoating. I've waterproofed a thick cotton bucket hat and Craghopper Kiwi trousers, all good. The trousers don't last as long because the material is very thin, moves a hell of a lot and brushes against everything. Works great on canvas trainers like Converse Allstars, confused my wife and daughter when we got caught in a downpour. Use it on all sorts of footwear and is really good for older boots (leather included) that leak slightly around the lace holes. If you're going to use on something like gaiters then you need to be really generous with it, you'll need to refresh it more often there too. I don't like plastic coats, I hate GoreTex stuff, the environmental impact of it is not justifiable for me and plastic coats are so so sweaty when soaked, yes even GoreTex. Very noisy too. You do need to recoat jackets and I prefer doing it by hand, find the washing machine method to be hit and miss. This has so so many uses. Once you've got it you'll find loads of uses for it.
