Dow Corning 791
13 Jun 2014
By whitedaz1983

" After trying to find a silicone that would stick to perspex (clear polystyrene sheet). This is the only one that worked for me. Other neutral low modulus silicones may work to. I would stay away from silicones that contain acetoxy when trying to stick to oily plastics. Only give 4star rating for reliability because it hasnt been on for long so I dont no how long it will last. "

Best ever sealant
6 Aug 2011
By chuckles

" Dow cornering 791 black is the best so far on the market.
I own a morris minor classic car that had a leaking windscreen rubber and no other sealant would seal it. Now no more puddles inside the car.

Dow Corning 791
8 Nov 2009
By scotbuilder
, South West Scotland
" We used this after being impressed when our builders used it. Put in very large pieces of glass. The seal is fantastic, does what it says on the packet exactly. We will use more of this product. Good outside and in the house. allows a little movement in the glass; what we needed here. Waterproof and allows for expansion and contraction on wooden soffits also. An excellent bond. Better value than other DIY products we have tried from big stores. We look forward to using this in other parts of our build to gain a good seal.. watch this space. Do not mistake this for glue though. reccomend it on all counts. also quick delivery. "

Rolls Royce of silicons

" Have used 100s of tubes on conservation project on north Cornwall coast. Excellent adhesion to stone and metal and wholly weather reliable product. Screwfix offering great price as normal but need to offer more colours - dark grey would have helped me. "

Good roof sealant
18 Dec 2014
By WestSussexWoody
, West Sussex
" Good stuff for sealing those very annoying corners on roof windows where the manufactures flashing is not up to the job. Also good for sealing gutter joints when using different manufactures products that don't quite fit as they should. A bit pricy for what it is though. "
