To repair a ~6" (~150mm) line of pinholes in a NeoAir camping mattress, what is the best repair material?

The line is too long, and the pinholes too close to each other, to use standard or emergency Thermarest patches.

I’m hoping for a solution that will last as long as the sleeping mat, and won’t significantly impair its packability.

    I use tyvek tape for house vapor barrier on packrafts. I think it sticks to most synthetic textiles and is pretty tough while being lightweight and cheaper than the gear specific options. For pinholes, aquaseal may also work. It’s a fluid you apply rather than a big piece of tape.

      Thanks for this!

      I’m unfamiliar with Aquaseal. If I tried Aquaseal first without success, and it failed, what would be involved in prepping the surface afterwards for Tear-Aid or similar?

      In other words, is the Aquaseal likely to interfere with subsequent membrane adhesion - and if so, how does one remove the Aquaseal from a NeoAir without worsening the existing damage.

      I’ve used Tyvek for other applications, but never for repairing inflatable items. Intriguing suggestion. I’ll look into it further.
