My view
Excellent product. Not easily found in stores

The perfect item to fill in gaps in wood on boats.
We used it extensively on the gaps in the teak panels that decorate the top sides of the hull on my sailboat. It’s been several years and they still look great.

Yin and yang
This is a 5 star caulking in a 1 star receptacle. I’ve just ordered my 3rd tube so I might complete my stunning project with this superior marine grade, sticky like tar, thicker than Arkansas mud, beautiful dark ebony caulking… the first two tubes puked out a small percentage of the caulking out the back (plunger) side creating a jammed caulking gun and loss of at least an ounce of the highest priced caulking I’ve ever purchased (that I’ve estimated approximately $2.59 of lost caulking per tube or the equivalent of 1/2 gallon of petrol in today’s inflated prices)… and I’ll probably purchase the same product next time hopeful that the supplier will decide to take care of their loyal passive aggressive customers by investing in a tube that’s structurally sound enough to function adequately to squeeze this extremely thick product into a tiny nozzle and out into the desired crevasse or crevice (depending upon the task at hand) without wasting a morsel out the tail.

Too costly to buy and store. Only buy what you need
Don’t buy it before you need it. It goes bad sealed in its tube.
