Plus smaller/lighter scratches to the left, lifting a heavy object out of the boot and it dropped onto the bumper :headbang: it's a very small area so not worth a full bumper respray
If its your daily drive... Then you could try a touchup paint mixed with lacquer... with toothpick to fill it... Building layers up... Then once dry buff polish it.
Build up layers with micro detailing paint brush until the deep ones are slightly above the original paint. Then you'll need to agressively attack the whole damage with wet 1500 grit sandpaper. Go to 2000 and then 2500 grit to remove surface scrub.
The whole thing will then need to be worked several times with heavy cream compound using a DA or rotary polisher, followed by lighter rub, finally a sealer and few coats of wax. This should get it to about 75% acceptable.
Unless you already own all of these levels of products or want 100% results, go see a pro.
What aquazi, powerontap, said but im not sure about starting with aggresively with 1500 grit, last time i did a repair like that, when my dad clipped the front wall on our works van :thumbsdown: i put one thin colour layer into the scratch then filled it up with laquer, 4 ish thin layers until the laquer was slightly higher than the the surface around it, then masked out the area around the repair and gently flatted until level with 2000 grit wet and dry, polished via DA to bring back the shine and it looks very acceptable
