This video details a DIY challenge to bulletproof car doors using readily available materials like porcelain tiles, construction adhesive, and fiberglass. The creators tested various configurations against multiple calibers, from 9mm to .308 Winchester. Key takeaways include the effectiveness of a three-tile stackup with matte finish porcelain, the superior performance of Loctite construction adhesive over Liquid Nails, and the significant benefit of a fiberglass layer for multi-strike capability. The Flex Seal was found to be less effective at holding fragmented materials together.

Quick Summary

In a DIY bulletproof car door challenge, a three-layer stackup of matte finish porcelain tiles with Loctite adhesive and fiberglass reinforcement proved most effective, stopping rounds up to 7.62x39mm. Loctite adhesive outperformed Liquid Nails, and fiberglass significantly improved multi-strike capability.
