Spray in bed liner in Dart trunk. Pics!

I used black Monstaliner in my trunk over Rust-Oleum red primer that I scuffed up with a pad. Monstaliner claims to never fade like other products. I used two coats with the supplied textured roller a few hours apart. I did this with the trunk lid removed.

The day after application, the vehicle was parked outside in the sun and the product began to bubble up in a few areas (It takes about a week to dry fully). Don't know where I went wrong and don't know yet if only the second coat lifted from the first coat or if the first coat lifted from the primer. Someday I will peel it off in a section that lifted and see what happened. Expensive stuff but the color and texture looked good after application.

May have been solvent pop that caused the bubbling. I would have kept it out of direct sunlight until fully cured. Did you give the base proper time to cure before putting on the liner?
