This product is terrible.
Dug out all caulk on our boat two years ago and used 4000uv as a replacement, huge mistake. After pulling the boat this year noticed caulk is turning into chalk. Not looking forward to another winter of redoing this because of a sub par product.

Lacks Durability
I am a professional recreatioinal marine tech with over thirty years experience and fully satisfied with multiple 3M products. However, based on product claims, I decided to try 4000uv beginning several years ago. I have discovered that it degrades in volume (wears away) and begins, in sections, to soften to an oily peanut butter consistancy that will wipe loose with a rag. 3M should revisit there testing protocols and remove or improve this product.

Burst Tube
I previously had good luck with 4200 and 5200 and decided to purchase a large tube of 4000. I am a little disappointed (based on the price of the product) that the tube burst in the gun and the product was wasted.

excellent product
We have used this stuff to seal in a wet, industrial environment for the last 2 years, Once it is set in place it does not leak or break loose like the silicone based sealers we have used in the past. It is difficult to get apart once set but that is great in my opinion its doing its job well.

Stays sticky
Bought 4 tubes fron large US marine store. Have used part of first tube and after two days it is still soft and sticky. Hoping it will cure before becoming contaminated with dirt etc.
Dissapointing to buy a product called 'fast cure' and have this problem.

Turned yellow and is now mildewed.
Application by professional boat painter in boatyard in May 2018 while out of the water. He used it to seal the seam between our rub rail and hull. It was Yellowed, mildewed/moldy within 2 months after being back in the water June 2018. Very disappointed in this product.
