Touching up scratch marks bike rack on boot (black metallic)

[EGBM87]

So.... put a new bike rack on the back of the car (68 plate) yesterday and wrapped some parts of it in an old rag to stop it from moving but didn't realise the metal strap buckles were digging and rubbing into the paint work of the car. Now have two lovely scratched areas around 1cm square that are very noticeable when you look.

It's a lease car so I'd quite like to get it sorted properly before it goes back (in about 18 months) - but I quite want it touched up just so I don't have to look at it for the next year and half myself!

Could anyone advise what the various options are and how effective they are? I have read about touch-up pens but I didn't know if these could make it worse or if they would sort it completely? I have no idea how much it would cost to get it done professionally either?

Any advice much appreciated!!

If you have no idea how to have the damage repaired professionally, search then .... ask.
There are masses of companies that offer to deal with dents & scratches so again search then ...ask.
If you mess with it yourself with paint pens & the like no professional will then want to touch it.
However in the dim & distant pass using a magnifier clipped to my glasses & a very very fine artiste brush with only a few hairs I have been able to fill-in scratches, but it took ages especially when the scratches were deep. The result was a poor compromise but then the cars were always mine so I was not obligated as to the quality of the repair.
You can bet that unless such damage is made invisible it WILL be spotted whenever you return any rented/leased car.

If after pouring water over it, the scratches vanish, then it's damage to the clearcoat and that can be buffed out using a good DA polisher and cutting fluid. If they do not vanish with water, then it's into either the colour or primer layers and will need touched up.
