Rated 4 out of 5 by from It's ok. It's alright, but there are better products out there. It drys to an opaque finish. I am sure it will be strong enough and not dry out like Poundland rubbish. There are better products that are crystal clear when drying, sika ebt for example. But you pay a bit more.

Rated 4 out of 5 by from Great sealant but let down by cheap casing. A high quality sealant that worked a treat for my summer house glazing. Sadly out of the two I bought the first one leaked heavily out of the base of sealant case upon squeezing the gun, thus almost 40% of it was wasted, hence only 4 stars.
