Hood paint issues '80 C3
The paint on my hood has bubbled and also sunk in some areas and for the second re spray. It is happening predominantly above the extractors so I am suspecting heat is the issue. Did the
C3's have under hood insulation as standard? Any advice on recommended insulation material or is wrapping the extractors the best? A common issue I am guessing.

The vettes did have insulation on the hood, you can get it from most venders. I am not sure that is the problem though. I have headers on mine and never had a problem with the paint bubbling. I went without insulation for about 2 years. I think your paint issues is with the paint and who it was put on.

the chrome bumper big blocks didnt have insulation so i doubt its from the heat. does it have AC? this causes hoods to bubble if the oil leaked and soaked into the hood. if this happened you will need a new hood.

I think there was just a post on the insulation..... i think it is a sound barrier.I have run without it for over 8 yrs without issues. I had my car painted in 2002. I now have some bubbles in other areas but I think it is due to the prep work.

This might be helpful:
Although both acrylic enamel paint and acrylic lacquer auto paint products offer specific benefits, they cannot be used together on car bodies due to their incompatibility with one another.
With surfaces properly prepared and under proper conditions, it wouldn't be a problem to spray acrylic enamel paint over acrylic lacquer auto paint; however applying acrylic lacquer auto paint over acrylic enamel paint will almost always result in wrinkling or other severe surface blemishes.
This is due to the solvent base in acrylic lacquer auto paint (lacquer thinner) being too potent for the soft materials used in acrylic enamel paint products.
