How to fix a door that got scraped?

yep, that's going to be as good as that will get with buffing.

you can play with the tiny brush and the touchup paint to hide it slightly more, but it's looking decent the way it is!

 

I say cut your losses and have a body shop re spray it.

 

I would get some scratch remover and polishing compound from Oreilly's and see how much you can fix it yourself before you do anything. You might be fine with the results and save a bunch of money.

 

Dude that will 100% buff out. Go get some micro polish and hit it with a fine micro fiber cloth for a while. Then ceramic spray from Turtle Wax or Meggies.

Your truck is still worth $40K LOL

 

It's down to metal and primer.

 

look at his latest finish job, specifically the reflection of his hand.

the edges of the scratch are tapered, which is the furthest point those scratches can be taken. any further and he's removing clear/paint. it's simply can't get better than that, regardless of whatever miracle gunk one uses.
