The Markron primer sealer 4-color pack offers a comprehensive solution for sealing and waterproofing cartridge primers, shotshell primers, bullet case joints and unsealed factory ammunition. It provides the added functionality of color-coding each cartridge for immediate identification of powder load and cartridge caliber. The pack includes four distinct, vibrant colors - red, blue, green and black. Unlike nail polish, which is susceptible to peeling, chipping and moisture damage, this product utilizes the original, proven primer sealer formula enhanced with unique coloration.

• This set comprises four bottles in the colors red, blue, green and black
