Carmine no stress cracks or spidering in over 75 cobra hoods like the one in the attached photo. We contribute this to the polymer undercoat.
I plated the underside of my ERA hood over 20 years ago and it looks exactly like it did when it was first done and it gets way hotter than anyonther panel on the cobra.
Newyorkguy,
The cost is probable equivalent to an aluminum body but our goal is not to try and replace any real metal surfaces but rather an alternative to it like in this case the fiberglass body was correct , fitted and in great shape not to mention way stronger than sheet aluminum. Its very hard to dent! I'll try to upload a video that would make a sheet aluminum bodied cobra owner cringe. I take a piece of PVC pipe and smack it down on a plated aluminum over fiberglass fender and no dents or damage to the fiberglass, now that's not saying if you drive the cobra into a wall that the fiberglass isn't going to crack but I'm saying the glass is less susceptible to minor dents.
