Clearcoat problem question.

I got my son's hood for his 90 Chevy truck back from the airbrush guy and started sanding on it this weekend after it sat in the sun for two weeks behind my shop. It has Nason Giallo Fly basecoat with Nason 497-00 clear as the base color and then flame stripes with Nason base and 498-00 clear over that. The problem occurred when I went to cut the dirt and bugs out of what the airbrush guy sprayed on the "stripes", I can cut it wet with 400 grit and when it dries, the clear still has a sheen as if it hasn't been sanded. I know he used 498 clear but don't know about the activator or how much activator he used. He swears it was mixed per the can directions. Any ideas on what might have caused this? I'm about to sand it all off and start over. The clear I sprayed over the yellow does as it is supposed to when sanded.

Thanks in advance.
