I had leaks around my marine speakers and one air control valve, I removed all pieces and laid a bead around each hole. I was able to check for leaks within 10 plus minutes. worked great. prior I tried standard bath and kitchen caulk didn't work.

Great product!

Small , slow leak in spa. Tried this 3x, no improvement. It's a risk. Worth the try before contacting store.

had a leaky hose after replacing a jet pump. This stuff did the job of sealing up that joint. It is a must if you are replacing your pump. Wish I had known to buy this with the pump.

Worked great 👍

Hot tub began loosing water rapidly. Discovered a leaky filter housing. Removed all the old silicone, cleaned well, applied the Boss 802. Let sit 24 hours since it is submerged in the water. Seems to have done the trick. No issues since. . Easy to work with and tool. Nice product.

ok great

Excellent product!

I use this in my pool and spa service repairs. Box store silicone caulk doesnt come close to sticking for long term repairs.

Good bonding product
