Repair or full respray?

[Abc321]

Any advice on if this is repairable or will need a full bonnet respray? Size is roughly 3” from left to right. Paint removed from pressure washer when cleaning it. (Potentially expensive) lesson learnt.

Follow up question would be how much? Audi Navarra Blue so readily available paint. I’ve already bought a touch up pen but think I’m grasping with that as it’s far too big.

Thanks all.
