Is there a black wax

It is a well known chemical defect from Dow in dark colored areas on most older motorhomes. Think it started early 2000's.

It happens when you go go from cold to heat/ heat to cold.

It's called paint checking. It will cost you about 10-20k to fix it. Do a google search
on " motorhome paint checking."

When we were motorhome shopping last year, it was on every Country Coach and Monaco we looked at. It's unfortunate, and most people just learn to deal with it.

Isn't that clear coat crazing? Whole nuther animal I think.

Black wax is is a "gimmick" IMO. I had a black Miata. Tried the black wax which did nothing extra to enhance the color or remove scratches any better than regular wax.

It's a 3 or 4 step process. Best to use a clay bar to clean the surface first then polish to buff out the scratches and wax to protect it. They have a black detailer spray that you use to buff at each stage. I have a black Harley, black Ford Edge, and a black F-150. Swirls are a fact of life unless you continually keep at it. Best if you use an electric buffer with different pads for wax and polish.

The black paint on my coach has very fine, smaller than hair line crazing in the finish in a few areas. Is there a black wax or something that I can put on to fill them. Seems like they used to make some color waxes that were for that very purpose but I haven't located it during an internet search.

You don't say what year your Monaco is but there was a bad batch of Corning fiberglass panels used in many different makes and models of coaches (including mine) in the mid 2000s that resulted in micro-checking in the darkly painted colors. The only repair for this is replacement of the fiberglass! :E
