Like many other owners and readers of the forum, we were totally happy with the finish on our C7s until we started to read how bad the orangepeel problem was.

I read all the posts on this forum about orangepeel and it's possible fix.

Posters with electronic measuring equipment are coming up with paint thickness numbers like 45-50 microns, which sounds like a lot, but nobody explained that 25 microns equal .001", except one post that did convert the thickness into inches and explained that a normal sheet of paper is approx. .003".

Yesterday I recorded on the DVR the show that showed the building of the 2014 C7, and made an interesting discovery when playing it back on my large screen plasma TV.

Something caught my eye when they were applying the FIRST coat of paint which was the primer. I ran it back, still framed it, and took a picture of it.
You have to ignore the morrey at the top of the photo caused by the lines in the TV and the shutter on my iPhone. It does not affect what I'm trying to point out.
Here's the picture.

You will notice that the orange peel has started on the very first coat of paint as seen by the reflection of the overhead light. That means that subsequent layers will magnify the problem, and in most cases wet sanding down the clear coat will reduce the clear coat to just about nil in some places.

I've been painting cars, planes, and boats for over 40 years, and my suggestion is, if the orange peel really bothers you, take the car to a body shop and have them add another substantial layer of clear.
Then stock up on a large supply of fine wet paper, blocks and compounds and have fun. In time you will get the finish you want.

Years ago, when C5's were still the current car, I was at a car show, and mentioned to the owner of a beautiful Dr. Blue C5 how orangepeel free his car was.
Asked him how long it took for him to smooth out the paint, and his reply was that this is exactly how it came from the factory.
Which proves that if all the planets and stars are in alignment on a particular day, at a particular time, at a particular moment, you can get a perfect factory paint job!!

No doubt about it, its the worst problem owners face in the C7, some dont care but as a painter/detailer, it drove me nuts. Id love another 2-3 coats of good clear.....

I wetsanded my car with 3000 grit for 20 hours or so and reduced the peel enuf that its gone in all but any situation where you get your eye 3-6 inches from the paint. I put back some thickness with a coating. You can reduce it , safely, but not get rid of it. That’s cutting it too close....

USCANAM, your spot on here. Have done a number of my own paint jobs in yester-years, primarily lacquer when it was still legal to use. Have a new Z06 on the way and if the planets aren't lined up for me on the day it's painted, I'll have to go to the trouble of having ample clear coat shot on the entire car.... Expensive, but well worth it if it matters enough to the individual...
