I can relate to you CalCruiser because I have been there and done that with our first rig
(CLICK HERE) which was gelcoat and no paint. It required lots of work only to get mediocre results. Barry T's product sounds interesting.
That is why I recommended to Ginny in the intro post, if she is considering lower body paint or no paint, it is wise to consider ordering her new PC in plain white paint only for the house portion to match the van color. Then add PC graphics to dress it up. Painting just the house plain white to match should be very affordable and so much easier to maintain a pure white painted PC that will be parked outside indefinitely.
Also save money and delete the Diamond Shield product. The Ford factory OEM white paint on the van surely doesn't need it. Use the money you saved on the fancy full body paint job and Diamond Shield to purchase other upgrades.
An all white PC will reflect most of the sun's direct heat. On a sunny day in a parking lot, place your hand on a white car, and then on a black car. You will quickly understand the difference a white painted PC can make. We always schedule our desert region trips to avoid the hottest time of year so we generally don't battle extreme heat. Every full body paint job does have an unpainted white fiberglass roof (as shown here) which addresses the worst, but our gray-painted sides can still warm up from the sun.

Regardless of all that, we have no regrets getting the full body paint job. 13 years so far and our PC still looks like brand new. But keep in-mind that we "garage" it when not using it. It washes and waxes nicely and looks great afterward. If kept outside all the time, I imagine it wouldn't look too pretty today. I have seen some 13 year old PCs being sold with full body paint that didn't hold up well. Most of the "ugly" is related to the Diamond Shield darkening & cracking, and also the clear coat failing.
Here is a section of sun-damaged Diamond Shield like clear film that GM placed in two places on the rear deck lid of our Saturn Sky. Diamond Shield can get this ugly being out in hot sun long enough. Removing these two small pieces was "Pure Torture". I could not imagine removing so much off a PC.
