Rubbery mess
Only time I've had an issue with this product. Had a hard time with this tube from the start and at the end of the tube I found this rubbery mess. As I used most of the tube, I'm hesitant about asking for a refund but it is a 1/4 of a $32 tube.

That’s it

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.

Preparation is key
I find this caulk to perform very well on my teak deck. But prepare well! Clean out the old caulk, clean with acetone, lay down a slick tape on the bottom of the groove so that the caulk only sticks to the sides of the teak and then apply carefully with blue masking tape protecting the teak itself. The caulk should last for 5+ years if applied correctly. Looks very nice!

Its the best.
I use this product to fill my teak deck seams. I have tried several different brands To do this including two part sealers & have found this to be the easiest to apply, long lasting, & looks good.
