I did a treatment of RaggTop a year or more ago and it is still going strong; I avoid doing anything but rinsing the top if I can help it now. With my first application I was washing the top and it didn't last as long - probably due to being rubbed off. I find the top gets clean with the RaggTop on it with just a strong water spray.

Definitely a wise move to mask off the rest of the car. The can claims it wipes right off, but it didn't do so for me on my paintwork. I use Zaino so it may be an issue of wax (what they tried) vs. Zaino (sticks like glue).
