Product is good
This product is very good. It cures very well and it sets properly hard. Good for industrial use. I used it in my car. For a coolant tank crack but unfortunately didn't work well for me, but the product is good.

Like molten metal
This really does set like metal & has excellent adhesion. I’ve often taken claims about “hard as steel” but this stuff is very good. I have repaired garden hose sprayers & load bearing brackets. It’s really effective.
