I got an inflatable wing board for traveling, and have used it a bunch of times to get used to it (and because I actually like it better than my wider hard board with the same volume). It has developed air bubbles near the foot strap plugs that are slowly growing. I've contacted the store about warranty, and the brand stated this would be an easy repair (injecting glue). Board repairs around here are typically done by a boat builder that's some distance away. I don't know how much experience he has with inflatables.
I think I can do the repair myself, but am not sure about what glue to inject. For hard board repairs and a few builds that I have down, I have used contact cement and E6000, both of which worked fine. But I'm not sure if they are ok for the inflatable, too.Has anyone done a similar repair, and advice on what to use (and perhaps other tips? Thanks!

First question, how old is it? Inflatables only last a few years especially if they are stored in hot places such as cars or left in the sun.
Once an inflatable starts to delaminate in places, it means other places will start to delaminate too.
So unless the board is quite new and has been treated well, it might not be worth trying a repair.
I would want a replacement board. With out taking off the pad and checking what's going on you have no idea of the defect. I can't see injecting glue under the pad sorting it, esp the pressure a board is pumped up to. My fear with an in flatable was it going down when I was a long way out at sea.
