This stuff is amazing!

Bought after today's Boatworks review to use in rebuilding butterfly hatches on my boat. I used it as window glass glazing and it worked great! Easy to dose with a standard cartridge gun and to clean with benzine. I glued the spots around the glass, laid a thick roller along the hatch, worked with an awl and pressed the glass into their recesses. I put enough pressure on the 795 to seep a bit on top and bottom to get 100% coverage, let it dry, cut it with a razor and boy does it look great and…

Expiration date is on sticker - Sealant won't cure - UPDATED

Pros
  • Pretty packaging
Cons

Dow Corning 795 Structural Sealant for marine applications.

I have used Dow 795 Sealant in the past with great success for sealing acrylic or polycarbonate windows, opening wickets and hatches on my boats that have no other fasteners. In this case I inserted a 3/8 inch thick sheet of polycarbonate into the sunroof's slotted wood frame. Dow 795 is thick and sticky, it is always best to cover ALL areas where you do not want it to stick or remove. Easy to apply with a caulking gun. The Dow 795 cures quickly, holds tight and I have had no leaks in boat…

Pros
  • Great for a small home
Cons
  • Questionable purchase for seniors
