Hold Fast developed Highland Dust as the fill for its own sealant and found it worked mixed into other brands too. Use one level scoop per 2oz of sealant. Small covers 80oz of sealant and Large covers 160oz, and that is the only difference between the two sizes.\u003c\/p\u003e\n\u003cp\u003eYou can pour the powder straight into the tire and then add sealant, or mix it into the sealant in a separate bottle first and pour or inject that in. Hold Fast reports the additive lasts anywhere from four weeks to the full life of the sealant, depending on which brand you mix it into; its own figures include 6-8 weeks in Stan's and 8+ weeks in Orange Seal Endurance. Whichever sealant you run, remove any dried formations and top it off every few months.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"HOLD FAST CYCLING","offers":[{"title":"Small","offer_id":45484100026412,"sku":"HIGHLAND","price":18.99,"currency_code":"USD","in_stock":true},{"title":"Large","offer_id":45484100059180,"sku":"SHOPDUST","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/HIGHLANDDUST.jpg?v=1777036210","url":"https:\/\/racycles.com\/products\/hold-fast-highland-dust-tubeless-enhancer","provider":"RA Cycles","version":"1.0","type":"link"}
