How many coats of paint?
 

How many coats of paint does Porsche do from the factory?

Email the Porsche museum?

Obligatory:

They dip them them, base coat dip, color dip, clear coat spray.

I thought they dipped the chassis for rust protection but sprayed the rest? Or did How It's Made Dream Cars lie to me....

You are correct, dip for the corrosion resistance, spray for color and clear. It is not very thick, and if it is like Mercedes clear, the last clear coat is ceramiclear. Very hard clear coat, and difficult to burn through.

Along the same lines, any insight on the wheels?

As others have offered and my info agrees with them, just one coat.

My source tells me the paint thickness can vary over a panel. The variation arises from the position of the panel when being sprayed. The more horizontal surface of the panel can receive more paint then the more vertical surfaces. Most notably the front fenders.

Why do you ask?

I'm assuming this was asked, relating to the many, many coats of paint applied on custom cars in the '50's, '60's and '70's. More was thought to be better and there were generally two kinds of paint, enamel and lacquer. The later was generally used on customs and was sometimes applied 20+ coats thick. It was quick to dry and could be wet sanded between coats. Often a translucent color known a candies was used and the more coats applied would create greater depth. Most of today's paint is water based and flat and only enough of a coat is applied to get an even and uniform coverage. More is not better. The top clear coat is what gives the gloss and protection to the color coat. The clear is generally chemically enhanced with activators and catalysts that facilitates curing, drying and sometimes heat lamps are used as well.
