PSA- Every Detailer oughta have some kind of magnification to inspect stuff like this. I find the oft-recommended ~30x way too powerful for *me* (especially on metallics), preferring a 15x lighted unit...man, I use it all the time just to see what`s (really) what, whether I`m actually gonna try fixing it or not.
Isn`t this called “solvent pop”? A question for the painters here.
Not a Painter, but...
Solvent pop can indeed look like that (I had it on my last e36 M3), but since this is *apparently* (key word!) oe paint that`s pretty unlikely. Much of the pitting in my `93 Audi`s paint also looks *exactly* like this, and it`s not solvent pop but rather just the effect of serious neglect in a harsh environment. In both cases, removing more clear did *NOT* make that aspect of the situation better (did help with the marring, but at the expense of making the pitting *worse*).
And solvent pop wouldn`t go away with the application of heat...won`t go away with the application of *anything* with the possible exception of new clear.
Whether it`s solvent pop (painted that side of vehicle) or early failure (that portion of vehicle exposed to...something), I`d still be after BMW to resolve the issue. And again, I would *not* be DIYing anything as it`d give them an excuse to shirk responsibility.
Ask the dealer to contact the BMWNA field service engineer for a visit. And that you want to be there for the visit.
Hey, that last bit is very important, glad you mentioned it!
It`s not at all uncommon for Reps/etc. to want the owner to *NOT* be present, and IMO it`s a big mistake to go along with that. BE THERE! And be polite, but be insistent about getting real responses to anything you`re wondering about (which might change in the course of the experience). Don`t fold (or get [ticked] off and lose it) if they try to blow you off; I`ve had some real, uhm...EXPERIENCES... in this situation. These days, I`d go so far as to record the whole thing, but then I kinda lean towards recording *anything* that could turn into a he said/she said situation.
