Seam seal X-Pac?

I haven't tried it on Xpac before, but I think it will work. The inner liner is polyester taffeta. Maybe email one of the fabric suppliers to confirm.
I usually use the flowable silicone just because it's easy to find and works well.

I have taped the seams on my X-Pac for years.

I used a permanent-bond transfer tape and 70 d PU-coated nylon fabric for this.
A tape such as 3M9485PC would suit, although I have used other transfer tapes as well.
All my successful bonding has been done on the lining side. Bonding to the outer or face fabric has not been nearly as good. The DWR seems to block the adhesive.

I haven't used an iron-on tape, so I can't say whether it would work. However, I would certainly give it a go as I think (think) it should work.

Thanks guys.

I hadn't even thought of a tape other than the iron-on type. I may end up going that direction.

I have found that Permatex Flowable Silicone sealant adheres well to the PET (Mylar) on Cuben, so it probably would adhere well to the PET film on X-Pac as well. Not to bond, but just to seal thread-sewn seams.

I've had success with seam grip too, fwiw.
