Use them for stringer fills, ding repairs, fin box fills, and foam sealing coats on foam blanks.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eCompatible with polyester and epoxy resins.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eMix ratio: roughly 3 to 5 parts bubbles to 1 part resin by volume, until the consistency holds shape rather than running. Mix resin and hardener fully first, then fold in bubbles by hand — power mixing crushes the bubbles and reduces weight savings. Let the fill cure completely before sanding.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eColor : White\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAvailable in 32 oz. and 2.5 qt buckets\u003c\/p\u003e","brand":"Greenlight Surf Supply","offers":[{"title":"32 oz.","offer_id":48840437170421,"sku":"665355974522","price":15.95,"currency_code":"USD","in_stock":true},{"title":"2.5 QT","offer_id":48840437203189,"sku":"665355974515","price":29.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/greenlightsurfsupply.com\/products\/3m-glass-bubbles-filler-powder","provider":"Greenlight Surf Co.","version":"1.0","type":"link"}
