Liquid Urethane Closed Cell Rigid Pour Foam 2 Lb Density - 1/2 Gallon Kit Total

So I used this to make a seat insert for my race car.I did not know how much to use... so I used the entire thing. I poured it into a trash bag and sat in the seat. The foam expanded so much that it pushed me out of the race car... foam got on me.. the car.. the seat... the steering wheel. USE SPARINGLY!!!!! Foam works very well. Hardens nicely and you can add layers. If I had read the instructions, this would have been much easier. I had to order more foam since I wasted the entire first batch. I recommend actually reading the instructions.

Excellent item. I’ve used it to ship expensive items on usps. Foam is sturdy. But it doesn’t expand a lot . So you must use a lot of the chemicals to fill in a void .

It mixes easily and creates a very sturdy, bouyant foam. Just a heads up that it begins to expand QUICKLY and you need to be ready to pour soon after getting a uniform cream. I'd say within 30 seconds mixed you'd better get it poured. Once it sets it is rigid and easy to cut, if needed. I bought it twice, so I definitely trust it.

Worked as intended. You do need to mix quickly and pour fast but very happy with the hardness and expansion of the product. I put a heater on area I poured and expansion went up considerably. Have ordered this item three times, happy every time.

Temperature was between 78 and 82 degrees F. Carefully measured equal parts by volume and mixed thoroughly for 30 seconds as directions indicate and then poured. No reaction at all and now I have a sticky mess in a hard to reach spot in the bilge of my boat. Tried a second smaller batch as a test in a cup and mixed longer. Same results no reaction.The jars were labeled part A and part B but they were both the same color and consistency while the image in the listing clearly shows part B is a lighter color. Not sure if its a packaging/label mix up or just a seriously sub-par product but I will be returning and looking elsewhere to finish my project.
