Rated 5 out of 5 by from Worth the money...excellent Really good grab and it holds fast whilst it dries. this was great to do some tricky fixes on my conservatory roof. Really easy to use and clean. I’ll use this again for sure

Rated 5 out of 5 by from Well worth the extra A more expensive sealant but if you are trying to stop outside coming in, look no further. Applied to polycarbonate roof around washers and adheres well. Went for white option as it cant be painted and I want to put solar reflective paint on next.

Rated 4 out of 5 by from Best sealants Have always been very pleased with DOW sealants as long as you get the correct sealant for the particular job. This one is no exception.

Rated 1 out of 5 by from Hard to handle Had to buy this last minute as I ran out of my other make. Unless you can get a perfect finish first time I would avoid this , starts curing as soon as you use it ,making it very difficult to clean up afterwards .

Is DOW 791 an acceptable alternative to putty when replacing a pane of glass

Asked by: stephenharryp
Hi thanks for getting in touch. This will be ok to seal the edges of the pane to the glass but putty will be better for bedding it in properly. I hope this helps.

Asked by: Shirlx
This dries to a standard clean white however is not a 'brilliant white' finish.

Would this be suitable to seal the external panels on a static caravan?

Asked by: KTaylor

How do I open it?

There is no hole that I can see for the caulking stuff to come out at, and I can find nothing there to provide a way for opening it to be able to use it?
