Frustrated with my 2010 GTR

Looks like the beginning of clear coat failure.
 
Have you looked if there is any tape lines around the edges of the area this is at? Cause it's looks like a bad repainted surface or an extreme overspray of paint. Open the hood and look for tape lines.
 
Looks like a bad clear coat spray that didn't smooth out, possibly from over spray nearby.
 
overspray? any paintwork done to it?
 
Definitely looks like it has been resprayed and had a solvent pop issue during the curing process
 
overspray or solvent pop.


In any event, get a paint thickness gauge on it before you chase it too far. That black nissan paint is very thin and soft, you don't want to go too hard on it.
 
I agree with the overwhelming responses. I looked at your pic's before reading the responses to the thread and the first thing that popped into my mind was:
1.) Solvent Pop
2.) Re-sprayed hood

Then I read the rest of the responses... So sounds like we have quorum.
 
Thanks for the overwhelming responses. I have check the paint with my paint thickness gauge it shows 135-150um range which it seems like factory area. I have no checked for tape line under the hood, ill do that today.

Will wet sanding this help? Or Is this below the clear coat layer?

Thanks again!
 
We need a few more paint measurements to be able to accurately recommend next steps.


Measure the hood in the affected area, as well as an unaffected area of the hood. Then take a measurement of a panel somewhere totally unrelated on the car: rear quarter, trunk lid, rear edge of a door.

Then take a measurement from the door jamb area. Manufacturers typically use a very minimal amount of clear in the jambs, so it gives you a general idea of how much clear you have in any given area outside the car.


If your jamb is 80 microns, and the exterior averages 120 microns, you know on average there were around 40 extra microns of clear to work with from the factory.


If you then measure the affected area it can go one of two ways. It either measures the same thickness as the other exterior areas and you know you're probably dealing with some kind of solvent pop issue, or it'll measure thicker and you're more likely to be dealing with overspray.

If it's solvent pop, I'd recommend getting the hood redone. It's unlikely you'll be able to improve this enough with the typical methods and risk going through the clear and having to repaint anyway. You could try wetsanding if you just want to experiment, but I'd recommend you do so with the full understanding that it's probably gonna go bad and you need to repaint anyway.

If it's overspray, you could try a more aggressive clay bar, or wetsanding to at least flatten it and shine it to match the rest of the paint with the remaining compound and polish steps.
