decals not sticking solution ideas

Hey everyone I’m almost finished with my pack build and put the decals I purchased from the GB Fans shop on a few days ago. Most are sticking just fine with no issues but the ones on the textured surface of the shell keep lifting at the corners.

I know what your gonna say… “I didn’t prep the surface properly before applying them” well I did lol they just don’t like the surface,.

I was thinking of using a matte clear coat spray paint to seal them and wanted to know what everyone’s thoughts were as I want to make sure the color and look stays in tact.
