PineDash Pro Tungsten Putty Kit combines 12 traditional tungsten weights with 2 revolutionary moldable tungsten putty pieces, giving you unprecedented control over weight distribution and final weight tuning that rigid-weight systems simply cannot match.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe innovation is clear:\u003c\/strong\u003e Traditional weights provide primary mass placement.

Some races may have specific rules about moldable materials—confirm tungsten putty is permitted. The vast majority of competitions allow all weight materials as long as total weight doesn't exceed the limit.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003eWhat is tungsten putty and how does it work?\u003c\/h4\u003e\n\u003cp\u003eTungsten putty is a moldable, high-density material that combines tungsten particles in a pliable matrix. It can be shaped by hand at room temperature, divided into precise amounts, and positioned in spaces where rigid weights won't fit. Over time (24-48 hours) it firms up but remains in place. It provides the same high density as solid tungsten (19.3 g\/cm³) in a flexible form.\u003c\/p\u003e\n\n\u003ch4\u003eCan I divide the tungsten putty into exact weights?\u003c\/h4\u003e\n\u003cp\u003eYes. Use a kitchen scale to weigh pieces as you tear them off. If you need exactly 0.3oz to reach 5.00oz total weight, simply tear off pieces and weigh until you have the exact amount needed. This precision is impossible with traditional rigid weights that come in fixed sizes.\u003c\/p\u003e\n\n\u003ch4\u003eWill tungsten putty stay in place during racing?\u003c\/h4\u003e\n\u003cp\u003eYes. Tungsten putty firms up over 24-48 hours after placement and maintains position during racing. For extra security, some racers use a small piece of tape over putty or apply a drop of adhesive. The putty's natural firmness is sufficient for most applications.\u003c\/p\u003e\n\n\u003ch4\u003eWhy use this kit instead of traditional weights only?\u003c\/h4\u003e\n\u003cp\u003eTraditional weights come in fixed sizes (½oz, ¼oz) which makes hitting exactly 5.00oz difficult—you often end up at 4.75oz or 4.93oz. Tungsten putty fills the gap (literally and figuratively), allowing you to add the exact weight needed for perfect 5.00oz. Plus, putty fills irregular spaces where rigid weights won't fit, optimizing weight distribution.\u003c\/p\u003e\n\n\u003ch4\u003eIs tungsten putty safe for children to handle?\u003c\/h4\u003e\n\u003cp\u003eYes, with adult supervision. Our tungsten putty uses non-toxic tungsten alloy (no lead). However, it should not be ingested and is not a toy. Adult supervision is recommended for children under 8. Wash hands after handling. Keep away from children under 3 due to potential choking hazard.\u003c\/p\u003e\n\n\u003ch3\u003eSafety Information\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-toxic tungsten alloy used in both traditional weights and putty\u003c\/li\u003e\n  \u003cli\u003eAdult supervision recommended for children under 8 during installation\u003c\/li\u003e\n  \u003cli\u003ePutty is not a toy—for derby car weighting only\u003c\/li\u003e\n  \u003cli\u003eDo not ingest—for external use only\u003c\/li\u003e\n  \u003cli\u003eWash hands after handling putty and weights\u003c\/li\u003e\n  \u003cli\u003eSmall weight pieces—choking hazard for children under 3 years old\u003c\/li\u003e\n  \u003cli\u003eTraditional weight adhesive is permanent once cured\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Precision Advantage\u003c\/h3\u003e\n\n\u003cp\u003ePinewood Derby physics is unforgiving. An underweight car at 4.85oz gives away free speed to every 5.00oz competitor. Traditional fixed-size weights make hitting exactly 5.00oz nearly impossible—you're always close, but close isn't championship-level precision.\u003c\/p\u003e\n\n\u003cp\u003ePineDash Pro Tungsten Putty Kit eliminates this compromise.
