  1. Rated 5 out of 5

    Works well–a highly dense putty. But, beware, since it’s a semi-liquid, it DOES run. I put it in my Pinewood Derby car with a hole on the bottom of the car, and it “leaked” down overnight. So, if you do that, store the car upside down. Or better yet, make the hole from the top!

    I received your product in the expected container undamaged. The 2 ounce metal container was easy to open. I had a difficult time removing all the putty from the container as the included plastic protector adhered to the putty. The instructions, regarding the putty use, you provided, via email, did not provide instruction regarding how to soften the putty, so I struggled extracting all 2 ounces of putty from the plastic and metal container.

    I provided a 3 start rating due to the fact that the putty stuck to the plastic and metal container and I lost approximately .1 ounces from my order. As you know in the Pinewood Derby world, weight plays a big role.

    I would like to recommend a researching containers that would eliminate the putty sticking to metal or hard plastics.

    Good Stuff! My boys are in Cub Scouts, and this was for Pinewood Derby car weighting. I’ve been unlucky with tungsten putty before where it’s too crumbly and hard to get to adhere. This stuff has great consistency – it was easy to adhere, but had enough balance that it was easy to work with and break down too to get to a precise car weight. I’ll definitely purchase again for next year’s race!

    Advertised as 2oz but that includes the weight of the container. Useable amount far less.

    Great product as always. Contributed to a 2nd and 3rd place finish in our PWD.
