    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.

    I’ve been working on pinewood derby cars for a while. I first started with my children, then the past 10 years holding derby car clinics.

    Tungsten putty is important to get your car to maximum weight. I keep the unassembled car weighted at 4.9 ounces. I drill a shallow 1/4 hole under the car and pack in the tungsten putty to make up the last bit of weight. That way on race day you can make small weight adjustments without trashing your car. The fastest car is the heaviest.

    I’ve been getting tungsten putty from the large online derby suppliers. I figured I’d save money in shipping, use Amazon prime, and try a new product. This putty is less dense than the putty I’ve worked with in the past. It seems to have more sticky binder and less tungsten powder than what I’ve used in the past. I ordered 3 units. They easily fit inside one container. I even mixed some tungsten powder to the 3 blobs of putty.

    I prefer the stuff I got before but this will work

    If you’re debating between the plug weights and the putty I would get 3.5 in the plugs and then 1 oz in the putty. The putty is really amazing for micro adjustments.

    I used it for adding weight to my flies for fishing, it was a little hard to get out of the container but it worked very well once applied.

    Great seller & great product! I used it on a slot car I am working on to run without down-force magnets.
