Flying season will soon be here, so I got an old model out of the attic yesterday. The wings are almost ready for covering, they are pink foam with obechi veneer and the LE and TE are already attached. But there are a number of bubbles in the veneer where it has obviously separated from the wing core.

What is the easiest way to stick them back down again? I'm not the original builder of this model (got it at a swapmeet) so I don't know what glue was used to attach the veneer in the first place. I plan to slit each bubble, squirt in some glue, then press it down flat. Which glue would be best for this? I've only done it once before on another model and it was a pain, it took forever! The one thing I really don't want is to get everything flat, cover the wing, then later find the bubbles popping up again.
