Odd paint defect - stone chip?
Discussion
Could I possibly email a picture for someone else to host/post?
Basically I got back to my car last night and it had bird 'poo' on it. I cleaned this off. all is hunky dory. I used my safe cut and i can confirm that the bird poo has not caused the issue..it just drew my attention to it.
Basically it looked abit like a blob of tree sap at first (see photo if someone can help me!). but i think what may have happened if that the lacquer has got chipped and then somehow the lacquer around has started to 'lift' a little. all other stone chips on this car have gone through to the primer hence my complete and utter confusion! the middle of the 'blob' looks like a stone chip that's been sprayed over. but it hasn't that's just what it looks like.
whole thing is well under size of 5p coin but it's really flaming obvious to me know.
how do i sort it?

so imagine that the 'blob' is maybe 8mm in total across with the sort of 'chip' bit in the middle like normal so maybe 2-3mm.
oh bugger it doesn't work - but if you click the link it will.

hmm annoying.
i was thinking you'd all come back saying it was something to do with the sun because it seems to have happened very quickly. and it seemed to happen this week - after being parked in the sun..!
it's quite odd because i have had a chip on the front wing (well cos it's a mini it's actually the bonnet!) which i must admit i haven;t sorted..and this hasn;t had the same thing happen.
maybe i need to get a detailer/paint restorer to have a look.
(i really don;t want to end up having to get the roof resprayed!)

Can't be a stonechip if there's no primer showing - even if clearcoat only was removed, you'd get paint transfer if you rubbed it with a white cloth and some mineral spirits or isopropyl alcohol (IPA).
I've yet to see any stonechip only affect the clearcoat, and leave the paint layer intact - if it's going to cause any damage, it's going to equally affect the paint layer as it is the clearcoat.
That's why stonechips are readily visible as whitish marks - grey primer layer visible.
It'd be extremely rare to only notice them on close inspection due to the paint layer having been undisturbed, which would make you think the clearcoat had failed.

that's really helpful. because it does come back to may original though that it wasn't 'my fault'. and also that i wasn;t going mad because i thought it always went through to the primer..!I've yet to see any stonechip only affect the clearcoat, and leave the paint layer intact - if it's going to cause any damage, it's going to equally affect the paint layer as it is the clearcoat.

I wouldn't normally disagree with PJ S - but I've seen loads of examples of stone chips where the lacquer is chipped away and the paint layer remains.
Not common with a factory finish, but quite common where a solvent basecoat has been allowed to dry too much before being cleared, or with solvent or WB when the panel temp was just outside the ideal window when the clear was applied. Both of these scenarios compromise the adhesion between the clear and basecoat without affecting good adhesion between base and primer, so the stone chips off the clear leaving base intact.
As for this defect, could be a piece of industrial fallout - a tiny, embedded piece of metal that corrodes, lifting the paint layers and creating the perfect scenario for panel corrosion, without any obvious chip or break in the paint skin - but can still be refused as a warranty claim as the cause of the panel corrosion is still "outside-in" rather than the other way round...

i am fully expecting to not get this done for free because i am sure there'll be an excuse as ever.
the man is supposed to be going to take a look at it today so we'll see...
if nothing else at least he should give me a reasonable explanation of what he thinks it is and why therefore it isn't a warranty issue...
but then again he wants the work so to a certain extent he'll want to get it past bmw gb or whomever..!

so it's been looked at and he thinks it looks like a stone chip that's been touched up.
i told it isn;t cos it's been mine from new. and i haven;t touched it up.
to be fair he believes me i think but now there's some rigamorole of having to get the 'warranty administrator' to have a look (because it'd cost more than £500 to sort).
i have no problem with this chap. he seems really quite reasonable. but i can sense it's going to run on and bmw will try and blame me..!

I dont think £500 to paint a roof is excessive. Admittedly is near the top of average, but you'll have over £150 in materials. Leaves £350ish to cure the problem, strip out as needed, quality masking, one, maybe 2 bakes and then guarantee the results for 3-5years. Sounds fair enough, actually, you'll get it done much cheaper if you shop around, but you get what you pay for!
