I have been using HazardDiscs from Golden Grub High-temp glitter I found through Ebay. Have made hundreds of lures this year and this glitter has not folded, flashed, smoked or bled due to the heat. The glitter shines very well and I'm very pleased with their product and will continue to purchase from them. Even after multiple heat ups, mixes and random plastic batches the glitter still looks GREAT!.
