That's a fiberlass wing, and not a re-paint over an original - right ?
Is there any defect along the seam on the front edge ?
After some years with my fiberglass wing, that defect along the front edge became a recurrent issue.
If present, could be a site for water ingress between the upper and lower halves of the wing from what I remember on how it was constructed.
I am faced with the same issue except mine is a foot long and three to four inches high. Picture later. I figured I would get it laminated like a gts wing.

Maine, it's the original rubber material. I wish it were a fiberglass GTS wing. That I can fix! LOL.
Dang Kevin, I feel better about this little blister.
I was thinking of injecting it with some type of epoxy and then clamping it with a couple blocks of wood.

Hah, I thought it was a fiberglass one.
The fiberglass wing I got rid off was just going to be a hassle to repair. Was becoming structurally unsound at the seams.

Would like to hear more about 'laminating'.
I got a good solid S4 wing and was going to have it painted along the lines of recommendations made here in the Forum. Can't find those threads in my files now, but wondering if it is the laminating of which you speak.
I use some glue called Goat Tuff that is used mostly in the archery industry, but is useful for all kind of glueing. I would first devise some kind of form that will match the contour of the part of the wing you are wanting to restore, then I would obtain a couple small vials of Goat Tuff and perhaps a couple of syringes and I would put the glue into the syringes and then inject the glue through the top rubber-like skin and into the void wishing to be eliminated. Then I would squish it around as much as I could to be sure the the entire void is coated inside then I would clamp it down with my form and leave it over night. I re-laminate the bottom edges of the 928 center consoles this way and it seems to really do a good job.
The trick is going to be in making the form to clamp with.

Sounds like good plan Jerry, but I would first want to determine if there is a way for displaced air to exit quickly (it may have seeped in slowly thru pores over time), otherwise if you clamp down the air will be forced sideways thru the foam and cause further delamination. The hole you make to inject the glue may serve, but should not be covered by the clamping form.
I would expect there to be about a dozen holes created with the injection process, and I would expect that the texture of the top surface and the bottom of whatever you use for a form will allow the air to escape. If not, put a couple of needles in it around the form and let the air out as you clamp it. On the other hand, the air will likely just be absorbed in the foam core of the wing. I don't think it is closed cell.
You may have to deal with some extra material, the larger bubbles appear to be larger in the concave then they were in the convex. if that is the case figuring out where to move the material will be the challenge. Test fitting before glue is a good idea.
I've done similar repairs with Super 77 replacing the nozzle with a tube nozzle like on some lubricants, with fair to good results.
I recently refinished the wing on the 88. Painted it with a very flat textured Polane being supplied by SW for a product we build. Very happy with the results, we'll see how it lasts. The point is, if you're going to refinish it, cut out the bubble, glue it down properly and fill the joints, you'll probably have a better long term repair.
Yep.
I spent almost 6 months trying to rehabilitate mine. My friend who owns a shop was trying to help me, so it wasn't a matter of money. He even said to cut my losses as it wasn't going to be worth it and start with new, good substrate.
Damn Kevin, I do feel a little better. That's definitely replacement time. I wouldn't even fool with it.
Thanks for some ideas fellows.
I may just vacuum bag it with some supplies from our composite shop at work, after injecting it with a bonding agent. We'll see. It's low priority at the moment, but still on the list of sh*t to do.
Is there anything a person to do to limit oneself to a similar situation ?
Is it caused from heat ? Or water ingress ? Freezing ? U/V damage ? I have never seen this effect before and it scares me a little ......
Its 30yr old foam, ...
Back in the day, there was a sprayable filler we used for hail damaged totals, it sands like Bondo, but it is semi plyable .
I would just sand the surface down to take out the bubbles, then recoat , sand, recoat, sand...and so on.
Today's products are made to make this type of job simple.
You could probably get a fair estimate from a local body shop.
