Yah, various degrees of care.
I just use the Spray wash using all options, pre-soak, hi-pressure, foam, rinse and the final wax...
Comes out nice, IMNSHO, but it will have some drops on it. Unless you get 5' or closer, you can't really tell. I could wipe it down with a towel after the waxing to get rid of the drops, but hey, it's a "Tear Drop" or "Water Drop" heheh, so I can rationalize that way. 4+ yrs? Yikes, I think still looks good.
I don't like the "Mirror Shiney" look and have actually had a few comments/complaint from Truckers saying the back shines TOO much, reflection... Not to worry, I'm getting a Huge decal for the back in the next couple of weeks.. heheh, fun eh?
The key for me is to stop off on the way back from a trip if dirty and that way it's done. I won't specifically hook it up and drag it down just to wash it. Hitting on the way home, right near by, is a quick stop, $10 in coins and done... ready for the next trip.
