So on Sunday, after Church and some other errands, I finally got to this at about 3:00pm. I used white microfiber rags, and the entire job was done by 6:00pm. The motorhome has 3 coats, including the cab, although the rear cap got one additional coat.
Here are the results:

The rear cap was the worst shape. Before:

Check out the ladder reflected in the finish now! After:

And finally, before:

And after (yes, I know it's the other side, but both are in the sunshine):

The RedMaxPro went on so easily, I couldn't believe it. After the very first coat, I could already tell that this was going to be a winner. After the second, I realized that 3 coats were likely going to be enough to finish. Sure enough, the only part that required a 4th coat was the rear cap. The entire MH shines like new, including the cab, and the color has been brought back rather than the chalky, dull finish that I've endured for years.
I used only a bit more than 1/2 gallon of the RedMax, so I might go ahead next weekend and toss one more coat on, as easy as it is to do, but it really doesn't need it. I sure hope that the reports are correct and this stuff holds up to the SoCal sun.
