I made no such error

Sorry thought you did and with the bad "shoot from the hip" info thrown around these days I wrongly assumed. My bad and I own it!!

yes there is and yes it is commercially available,

I would really appreciate it if you could steer us all to a more highly adhesive polysulfide suitable for use in the marine environment that is also bellow waterline rated and has 1000 PSI adhesion?

I think many would be interested in this product!

I am fully aware of that! I mentioned after dog to reiterate a good point. I've worked in three different boat yards and have seen MANY products from portlights to inclinometers ruined by Life-Caulk/Polysulfide. I love polysulfide it is my sealant of choice next to butyl but you need to understand when and whre to use it that's all.

Yes Life-Calk or 3M 101 would both eb great choices..

Oh and your list of caulking products is short by several thousand adhesive/sealant products

I do know my sealants fairly well, at least the marine rated ones. No commercial boat yard I have ever worked in would ever consider using a non marine or non-bellow waterline rated product. While there may be better products out there the insurace companies would have a field day if a boat sunk because a boat yard used a construction trade sealant not specifically rated so they usually don't.

Of course my list is short and I tried to keep it succinct to what you may find in a marine chandlery . I did not mention any of the boat builder/ marine trade specific stuff such as Plexus because they are hard to find and especially in small volumes & no one on this forum wants to buy a 55 gallon drum..


Sorry for thinking you were confusing polysulfides with polyurethanes! We would all like to know about this commercially available 1000 PSI polysulfide product..?
