Try some of this: Paint Glaze, 16 Ounces - Griot's Garage
My service van has a full-body vinyl wrap, and I also brushed across some bushes. While the scratched vinyl was not glaring, it was bothering me. I am a great fan of Griot's products and have been using them almost since they started, over 25 years ago.
This product performed exactly as stated. The scratches did not go away, but were almost invisible after use.
Try it…..you'll like it!
