Good cap system
Did the job I needed to do, very useful cap system works well, no messing about cleaning nozzle etc after use, next time you need it it's ready to go.

This sealant is basically a goth superhero in a 280ml tube. It sticks to brick, concrete, stone and wood with impressive determination—and the black finish makes every repair look mysteriously intentional. Easy to apply, weather-resistant, and excellent at filling awkward gaps. Sadly, it did nothing for the emotional distance in my family, but the shed is now watertight. Five stars.

Good but tube design is rubbish
Good sealant but the tube has got stuck in the gun and I can’t get it back out. I’d take the old tube design over this new design any day.

Excellent product
I purchased this product a few weeks ago to use around my new kitchen sink. It was easy to use and clear away any residue making the installation problem free

Easier to use
I am not good at using silicone but this was really easy to use. I’m impressed and have bought some while to use in my kitchen. Smell is strong though and lingers for a day or two.
