Orange Peel !!!!!!!!!!!!!





I think the dark color and metal flake hide it well, but LB has it too.

Thanks to regulations trying to protect the planet, automobile manufacturers that painted their vehicles in the USA are required to use a water based (I think) solvent for spray. The solvent used is not terribly effective of completely dissolving the mixture and there are times when minicscule "chunks" of the media (pigment or clear coat goo) will remain in suspension. This gets sprayed onto the vehicle and when dries has a raised appearance, because it is raised (even if only 1/100th of an inch).
The Corvette (C5 especially) has a noticible orange peel because the paint required for the body panels (flexible and can expand slightly in the heat) is particularly hard to dissolve. Often there is little or any problem, which is why there are owners who have no issues. Other times...well...
The only way to truly fix this (and remain legal) is to inpect each and every batch of clear immediately prior to spray. With tens of thousands of vettes being produced annually, that is never going to happen.
Light colors and metallics will show the least because their surfaces are already reflective and in the case of metalics are "sparkly" so any reflections caused by orange peel would be "lost" amoungst the paint. That's not to say that it isn't present, but it is less noticible. And dark colors, black especially, have the uncanny ability to show off every single flaw in the paint and thus exhibbit the most complaints.

but it would add several hundred dollars to the cost of the car. to remove orange peel , its a simple matter.. the problem is gm uses robots to paint these cars... they put out to pasture all those human painters... and the guys who use to block sand between coats...when acrylic laquer was the paint of choice.
anyone who has uses a spray can know it is impossible to deliver paint that is flat... everyone block sands the application cutting the peaks down to the valleys then applying another coat , cutting those peaks untill you have a very flat and thick valley area .. with a reflection like a mirror.. because there or no more peaks and valleys..
I wish some of these newbies who come here posting their BS... would do more listening and less filling the forum with their made up crap...
you could take a piece of very rough wood... clear it, and sand it smooth and flat and it would look like a mirror... the rough wood would still be rough but the surface of the cleared piece of wood would be smooth and flat and very very refective... I its only the top coat of clear that is the issue... about .0005 of an inch, thats 1/2 a thousands to those who dont do tenths.

BKNBLK- Do you have a pic of your car that shows how bad it is?

With that said, I would think that the automotive industry could regulate those parameters more closely to eliminate most of the orange peel affect. But then again, they may be wanting to make sure the paint is on thick enough and would rather have the orange peel outcome rather than risk having the paint applied too thin and dry.

I clay barred the hell outta the hood, used 3m swirl remover for dark cars with a random orbital, and then zainod (z5 and z6) with over ten coats.
Probably overkill, but this is how it came out--
wish I had taken "before" pictures though:
Anyway, I think orange peel is great -- gives a nice "hammered metal" effect!

As in my previous post, I think this article pretty well sums it up.
