ouch... :x
Well one of them is obviously a poor attempt at a repair... shame it's on the curve of the wheel arch...
Touch ups on silver paint don't really work due to the way the flakes lie (different from brush to gun), so I wouldn't try that, I'm afraid that is a repair job...
Something like chipsway could help, I know a lot of people seem to moan about them, but the whole point is that if the job is good, you’ll never know about it… I’ve seen (well measured) plenty of cars that have had great spot repairs…
the other thing you could do is a rattle can job... spend some time getting everything taped up around it, and try to build the paint up... a kid of DIY spot repair if you like... it could make it look worse mind you....
The others, well certainly the first looks like lacquer failure, again something that requires paint work… a few ways to do it… for very small repairs I brush the lacquer on, and wet sand/denibber it down to blend it… although this isn’t always 100%, or you could ‘blow in’ new lacquer, or have to repaint the panel… again, not something beyond the capabilities of a good chipsway type person.
The other 2 seem to be either damaged lacquer, if so see above, or have a load of fallout on it… if it’s the later, get some decon gel onto it (they usually turn purple with contact – something like Iron X or Wolfs Decon gel) then clay the paint – not sure if you have already tried it…
If it is fall out, then the above steps should clear that up nicely…
