Excellent sealer with real grip
I can't say this stuff is easy to remove once applied as the only time I had to remove a piece I had used the product on it put up a heck of a fight coming off. That proved that it had created a tight seal which is what I wanted. Vibration wasn't going to lossen it that's for sure.Application can be messy if you get in a hurry but its ability to create a tight seal with a firm holding power would be hard to duplicate this side of a weld.

If you are using for high temp (exhaust) applications, it will not stay flexable
Thought I would save a few by using Optimum Black...Had to replace with Optimum Red which stayed flexible at the high temp.
