Dowsil 799 Plastic & Glass Silicone Sealant 310ml Clear is rated 4.5 out of 5 by 20.
Rated 5 out of 5 by from Ideal for perspex. Adheres to perspex glazing panels and wooden frames very well. Cures quickly so I did one panel at a time. One tube was plenty for 3 doors each with 5 panels plus a window with 2.

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 5 out of 5 by from Could be better. Not the easiest to work with but does the job. Fitted some lexan sheets with it.

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.
