Best advseive for PVC fabric patches

[Sylvan M]

I just got back froma trip where I did a hasty patch n go patch on a tear.  Now I owuld like to replace it with something permenant.  I am confused as to what adhesive to use though.  The Alpaclka site says you shouldnt use aquaseal for patches where the air cant reach it, like adding attachments or fabric patches, but then when you buy a fabric patch or attchemnt form them, they send you aquaseal as the adhesive.

 

My questions:

Is aquaseal ok even when air cant reach it to cure? like for example adding a tie down anchor or putting on a non-tape patch?

If not, what should I use for long term fabric patches?  on eurethane?  on PVC?

I’ve also heard that aquaseal won’t work if it can’t air-cure. If you email Alpacka, they’ll tell you they recommend this for tie-downs and whatnot:

I used it to attach 4 front tie-downs to my Curiyak, and they’re still strong years later. I also used a 1/8″ roller to push out the air patches:

I applied a thin layer of glue to the boat, then to the tie-down. Then immediately another layer to the boat, and also to the tie-down. Then a third layer again to both. Then I attached and rolled (for several minutes) and waited 24 hours.
There’s a little more detail in my post here:

Those thigh straps have taken a lot of stress and show no signs of failure, so that glue is golden.

This might help (one should always check with the manufacturer of the raft first):
