Easy to apply--strong bond

This product was easy to use and provided a nice seal that bonded the upper and lower case of my washing machines transmission. IOW, the oil did not leak or seep out, which was the goal.

Great Sealant

I have used this sealant for years on most everything that needs to not leak. It bonds quickly and is easy to apply. I always carry an extra tube in my tool box.
