Heat Sealing Airtight & Waterproof Fabrics with an Iron (2023)

I've been making inflatable boats since 2015, and in this video I present what I've learned about welding TPU-coated fabrics together using a handheld iron. It's an updated and more thorough demonstration of techniques I've presented in some of my other videos, plus some new information. I hope it's helpful!
