bad touch up or rust bubble

I was detailing my car and then I sow this. My heart skipped. I'm the second owner. Car has never been hit or accidented according to carfax.

How can i tell if its a bad touch up paint or a rust bubble.

Note: I got it inspected at the BMW dealer but I need your feedbacks first.

I thought galvanized steel won't rust :

You'll find out what it is when you have it fixed, which you should do in any event.

BMW accepted to fix it under warranty unsure yet if it's caused by rust or a poor touch up paint .

That's what I'm thinking as well, but what makes you say that? I'm curious

It doesn't look like it was applied to the surface to me - that's why I think rust from beneath the paint. Glad to hear warranty will cover it - you just need a competent shop!

The only way to know for sure also happens to be the very first step in fixing it, wet sanding it to flush. If it's just a glob of touch up paint the only thing wet sanding will reveal is more paint.

I guess ... I'll wait and see what bmw reveals . Makes me hesitate now about getting an anti rust treatment . The car is like brand new and I'm keeping it for a long time, but yet most ppl are not recommending it , including bmw . If it ends to be just a bad touch up paint job , I'm might not do the treatment. I don't know...
