Used to secure new wall panel in a boat locker. Works as designed. Easy to apply with caulk gun and after 24 hours it’s setting up and holding firm. Cleanup up is typical, paint thinner or stronger. No idea on longevity, but it appears to work properly. A huge savings over big brands. It does seem smoother or thinner than big brands but works well and is easier to use. I will purchase again on my next project.

Good stuff. Worked well on the boat, and it adheres to silicone which is a plus. Has held up well in my last couple outings on the boat, so no complaints on water resistance.

I used the 3m version of this that has started to crack after 2/3 years on my boat. After one use I am impressed with this, it applies smoother than 3m and has held up better over the past 3 months than the brand name stuff did. Much better value and it seals well. I will update this after a year or two.

I have used this stuff for everything on my RV build. I even used it to melt a plastic block to my boat transom to melt my transducer. Highly recommended.
