What we liked
- + Steel reinforced with a stated tensile strength of 5020 PSI and heat resistance to 550 F
- + Once cured it can be tapped, filled, sanded and drilled, which helps when shaping a repair
- + Listed for metal, plastic and PVC, wood, ceramic and fiberglass surfaces
Trade-offs
- - Slow: 4 to 6 hours to set and 15 to 24 hours to cure, so parts must stay clamped or supported
- - Cures dark grey, so it is unsuitable for clear parts or any joint that stays visible
