metallic paint failure - wbd
My Astra estate SRi -1992 has metallic paint in dark grey/black, this has devoloped circular patches of 'non-reflection' highlighted at the edges (whitish circles)on the bonnet. Its as though the 'varnish' has been rubbed away.

What causes this and how can be cured?

It sounds like a clear cote failure to me. where the laquer is seperating from the colour coat below. The cause can be all sorts of things, most likely where stone chips have been and over the years allowed water to get between the layers of paint and laquer.

There is no fix i'm afraid other than a respray.

My Alfa 75 had this & according to a body shop guy it's down to bird droppings etching the lacquer & not being cleaned off quickly.

Seems reasonable, also sap from the neighbours high hedge, probably exacerbated by engine heat and hnce only on bonnet.

those old astras with metallic paint did this with most of them whether they were metallic red or even silver,if you scratch the paint you will find that it is not affixed to the base coat primer and therefore the lacquer used to fall of in sheets
estates used to suffer worst
