My bumper got a bit scratched up from a small fender bender. here's the damage. Scratchx works pretty well. 2nd pic is after I used scratchx 2.0. I have some factory touch up paint but the scratch is pretty deep. Should I use langka, paint scratch...etc?

 

The really wide white scratch is that too the bumper or just paint only?? most of that will buff but seems the wide scratch may chipped and that will mean new paint job!

 

I'd use your touch up paint on the three white areas, that should hide it pretty good.

 

That just looks like paint transfer to me unless the bumper is used and came of a WDP. If it is just transfer, a little paint thinner will take it off.

 

If it's the paint rub off then take a rag and some brake fluid. VERY LIGHTLY rub off the excess paint. Immediately wipe with water.
