Fixed car leak
We used this sealant to seal some cracks in our Honda that were causing water leaks. This product was easy to apply and sealed the cracked that was causing the water leak. I would recommend this sealant as a cheap and easy solution for water leaks in cars.

Expensive but worth it
We bought a new boat and my husband put the motor on. This is what he used to make sure all the holes from mounting the motor were sealed. We have had our boat out a lot and this product has stood up to all the water with no problems
