Meet expectations.

Good stuff, There's definitely a learning curve, but that's on me. Using between thin fiberglass sheets (Boston Whaler resto) I appreciate it's ability to maintain some density even when allowed to expand freely, without deforming the skin.

This is good stuff, not soft, squishy foam. Very high density and tough

I used this product to pour through a small hole into an area that an animal was attempting to dig under my deck. It expands pretty rapidly and you need to get it poured as fast as you can after mixing it. You have maybe a 60 second working time before it takes off. It expands very rapidly and voluminously. It filled the area with decently hard cured material. Just don't put it someplace fragile and confined, it will very happily push out thin wood on its way to full expansion. The end material seems acceptably durable. It builds a thin skin on itself and it's not easy to rip apart or dislodge. The resultant material also sticks aggressively to anything, so make sure you are ok with that. Also, don't get the pre-cured material on your hands; it sticks extremely well to human skin and it will be a pain to get off. Overall a great product for filling spaces!

Measure equal parts into 2 containers. Pour into a 3rd container and stir for 20 seconds then pour into what you want filled. I used this in an aluminum sectional flag pole to make it rigid for use as an antenna mast. Worth noting, when this starts expanding it does it FAST if it’s hot outside. 1 1/2 fluid oz. of each part (3 oz. total) expanded to fill 13 inches of a 2 inch hollow pole and this stuff is hard as concrete but super lightweight. Wear gloves as you don’t want to get any on you and it does heat up when expanding and curing. It only takes 5 minutes or less for full expansion. Expands probably 10x the volume when mixed properly. This is great stuff.
