My apologies on the insurance thing. No fault state is a different story.
That paint from what I can read on the can is base coat. IE should be clear over it.
Is it just the bumper paint or is the bumper same color as the truck?
Couple things you can do easily to sleuth out the paint situation.
1. Open that can and paint up the scratches and see if it matches. Then you know the paint code if it does.
2. Find an inconspicuous spot or frankly anywhere around the damage that needs repaired. Sand it a little bit with some fine sandpaper. 1000 or finer. If the dust is white it’s clear coated. If it’s brown it’s single stage.
3. If it’s brown, hand polish the same spot with compound or polish. If it shines up quickly, it’s likely original lacquer or old acrylic. (Soft paint by today’s standards) If it doesn’t , it’s newer paint.
Good luck.
Subjectively, IMO you need a little one man body shop kinda guy, not a production collision shop. Someone who will take a few min to be creative and match something up that works.
