Well, water was coming through my roof. After applying this product the water is now staying outside.

I used this Surfmist colour silicone to fill in small holes in my colourbond fence after removing small screws that had planters attached. It matched the fence colour 100% and now painting it with the Solarguard paint using the Wattyl colour Atta Sierra B20, C24, F2 instead of the Colourbond paint. I used my finger for the small holes as it was easy to push the silicone in and pat smooth.

Used this to replace old dried up silicon on exterior tiles. Since replacing there has been no further leaks or water running where it shouldn't. The transulcent (clear) silicon is perfect if you are not that skilled at using silicone.
Works as expected. Use a caulking gun of course and you will get a much better result. Using warm soapy water to push it on properly saves a mess.
One of the best roofing silicone on the market, works well
Works really well. I repaired a clothes washer seal, then the next week used it to seal replacement taps.
Great product, colour match was perfect. Easy to work with. We’ll see what long term durability is like.
I bought this two weeks ago during lockdown level 3 in Auckland. It was sooo easy and well organised. An amazing system implemented by Mitre 10. Well done!
I have used Selleys Roof & Gutter Silicone Sealant to seal a number of small leaks in a section of corrugated iron roofing. It works well.
