Your Trade Wind looks great. Make sure your trailer has all the clear lacquer stripped off. It almost looks like there is some still on it. I prefer to compound with F 7. It takes a little longer, but it produces a better result from my experience. Then I compound again with C, and cyclo with S. I find F 7 works well for my yearly cyclo polish. It cuts stains, but still leaves a pretty good finish. S doesn't do much. My trailer is an 86 and not AlClad aluminum, so it doesn't get as shinny anyways.
