Repaint Bumper after Deformation?

[Shedding]

Someone has reversed into my car and scratched the front bumper. The bumper must have deformed and then sprung back into place as there are also cracks in the paint perpendicular to the scratches. If this bumper is repainted, will the past stressing of the plastic bumper affect the new paint either immediately or over time? Also, will a paint shop be able to match the metallic black of the car (factory paint) without having to blend into adjacent panels?

I'm wondering if I'm better just disguising the damage with black wax and waiting for another bumper to appear on Ebay or the like.

Thanks for any help.

How deep are the horizontal scratches? A lot of that might buff out and you then decide it's not worth worrying about

They're quite deep, they won't buff out, I've tried.

That's what I do in these situations. Too much risk of getting a proper £1,000 repair and then the same thing happens again.

The car is pristine otherwise and I haven't yet found a suitable used bumper so I am keen to investigate getting this one painted but only if the stress lines won't affect the new paint and blending into other panels is not required.

When my bumper had been bumped they just heated it up to pop the crease out then filled and painted as normal. Likely with a flat back in the middle.

You can't paint over cracks.
The cracks will need sanding completely out, so needs to go back to the bare plastic & starting from there.

It shouldn't. Assuming the plastic itself isn't cracked.

They should be able to.

Tried with what? By hand, or machine?

Thanks, that's really helpful, I'll contact a local paint-shop.

By hand with some medium polish. It didn't make the any difference. I think the scratches are through the clear-coat and into the black coat, possibly through that in places.

Whilst you're probably right, I think use of a dual action polisher would make that look significantly better.
