Is there anything I can do to lessen the deep scratch on my Fit? Thanks

 

Sure.


Buy some brush-on touchup paint (use the paint code, on USA cars the paint code is on the drivers door VIN sticker).

Then roughen the inside (darker) area of the scratch with a pencil eraser. Clean with rubbing alcohol.

Then, paint the scratch with your paint. Apply multiple thin layers. You want the painted surface to be higher than the surrounding surface. Let dry for two weeks after you have the correct thickness.

Then, you can use wet sandpaper to sand it down level. Use a very fine paper (2000 grit) and try NOT to take the OE paint off the surrounding area. (Many light strokes are better than a few heavy strokes...use the weight of your hand when sanding, do not press down.

Alternately you can use a product such as Langka
Langka - Paint Chip Repair

or Dr. Colorchip
Dr. ColorChip Automotive Paint Chip Repair Kit - Dr. ColorChip: Automotive Paint Chip Repair Systems

These include paint, and use a solvent rather than sandpaper to "level" the repair.

You will also have enough material to fill the abrasions I see, lower on your bumper.

Good Luck!
