Hey Frank,
I've tried that liquid cment trick once before. I have to say, it works, but it's a very fine line between set decal and goopy mess. I consider myself lucky that I quit adding cement at the right time.
As for this current siuation, I layed down a heavy coat of Future and it seems to have pulled most of the air out from under the decals. But, the decals were printed on clear paper, so they're not very opaque. Blue Angels yellow doesn't really cover over BA blue, so well.
I ordered some decal paper from micro-mark, now I'm just waiting for my order of printer ink to arrive. I'm hoping to have the Bearcat finished by the weekend (if the ink shows up).
In the meantime, I'm working on the F9F-5 (F6F and F9F-2 are done).
