looks like cheap product failure ,maybe 20 or 30 years back there where good single pack systems available but nowadays they seem to junk aimed at so restoration home hobby aplications ,the cracking slash splitting could well be due the clear going brittle over a softer basecoat
Maybe your point on the brittle clear over softer base could be right. I was new to painting and only spot primed areas, and the basecoat took a good 6 or 7 coats to cover because of this multi-toned background. The again, it’s also done it on the rear valance which only had 2 or 3 coats of basecoat.
The car hasn’t even been out of the garage yet and there are no windows.
I wonder if a water based basecoat would help as it would be less vulnerable to solvents in the clear? There is a binder which you can add to 2k paint which makes it air dry, maybe I will try that as I don’t want to expose family and neighbours to isocyanates, let alone myself.
TBH I’m a bit fed up with it as I’m also fighting to work over a poor respray on the rest of the car.
