To stick or not to stick that is the question....

Sounds like dry time couldn't be the issue; you have real patience.

I dip-prime with a 50/50 mix of BIN Cover Stain/VM&P Naphtha and then spray a coat of Rust-Oleum Painter's Touch 2X primer (which is what I assume you are using -- Rust-Oleum has several products with "2X" on it.)

I spray Rust-Oleum lacquer as a basecoat before airbrushing. I've never had a primer-to-base coat failure using a lacquer base coat. They are both Rust-Oleum products so they bond well. I've also never had a failure between any airbrush paint and the Rust-Oleum lacquer base coat. This would literally add another layer to your paint work, but I'm confident it would eliminate the problem.
