I have an '07 civic that has a paint defect on the hood only. The rest of the paint looks good but the hood has these small star shaped cracks. I didn't realize how bad it was until I used UC with lake country orange pad followed by 205 on a white pad. These little star shaped markings can be felt slightly if I run my fingernail across them.

I not sure if I could wet sand them out with 3000 grit or not. The UC with orange pad was not able to clear it up.

clear coat failure unfortunately. Beginning stages atleaste
 
Those are crows feet or Lacquer cracking:

Problem
When you diagnose paint with clearcoat fracturing, this is an indicator of a problem with the clear layer of paint.

Clearcoat Fracturing cannot be fixed by machine compounding and polishing as the fractures are like millions of stress cracks that run throughout the entire matrix or thickness of the clear layer of paint. Abrading the paint will just make the pant thinner and expose a deeper portion of the fractures.


Solutions

Live with the defect
Best recommendations are to prep the paint accordingly to insure the surface is clean and smooth, that is clay an polish if needed, and then maintain what lifespan is left in the paint using a premium quality wax, paint sealant or coating.

Repaint
The other option is to have the panel or component re-painted.​

Hi Mike,

How about this?

It seems like they are calling it crows feet. Now would you consider that clear coat fracture or clear coat failure?

Thanks.

I would continue to call the defect in the above picture and link you shared crows feet or in the old days it was called lacquer checking, or lacquer cracking.

Both Lacquer Fracturing and Crows Feet are both a type of crack or fracture in the paint but have a very different appearance.
