One brand of paint has had these issues (and as stated earlier - Merc Benz product has suffered badly with this micro blistering especially on red vehicles).
The MB warranty process states that all the paint must be removed and the vehicle painted from substrate i.e. bare metal.
This is what I would be asking for here with this S5? I would also NOT be settling with just certain panels, I would want the whole car painted.
You might also have colour mismatch concerns, with just odd panels being painted?
Also what if the un-treated panels "flare-up" in 2 years i.e out of warranty....
