I know the frustration you are having with these spray paints. I just finished my winter project in base Lustrekote silver with black and yellow trim. All colors lifted when masking tape was used for the next color, I let the paint cure 3 days before applying masking tape so it should not have been a cure problem. I finally used automotive paint for the black and yellow, and some Chevron Perfect Paints silver, it was a perfect match to the Lustrakote, but it runs easily and seems like it never wants to cure. I have sworn off both Lustrekote and Chevron spray cans. I have been able to utilize Chevron in a can with my airbrush. It too took quite some time to cure but it left a beautiful finish. It sounds like you have a pretty high degree of spray experience so you might want to give the canned paint and airbrush a try.
