It is clear that the metallic base is separating from the primer or primer separating from the substrate possibly due to oxidation. Hence the mini-mountain/bubbly look in the paint. Metallics sprayed on poorly sanded primers can look like this, too. Sometimes paint shops will sand the primer and let the car sit for a while before painting, causing a hard film to form on the surface of the primer and thus, poor adhesion. This sucks because the customer gets a nasty surprise as early as a few months following painting, or sometimes a few years down the road. Finishing is an art, prep and staying within recommended paint manufacturers time frames for applying subsequent coats is paramount to a good/long lasting paint job.

+1 looks like poor prep work, although I've also soon pool chemicals spilled do this as well (but since you're not cleaning pools I don't believe that would be the case
