I've never had this issue .

Now I've certainly come across bad decals that were brittle and/or the adhesive had degraded so they were weren't going to stick to anything very well .

I don't buy the air under the decal reason .

I don't know how you could get that much air under a decal with proper application .

Plus . I've microsol'd down decals atop all kinds of terrain , including 1/35 Zimmerit .

I don't believe the film is gas impermeable when saturated with decal solution either .

Not saying air is never the reason but ...

The problem once the decal is affixed with those delaminated portions present is the tented area can't be flattened without debonding the surrounding film to allow it to spread out .
